Figure this out and you'll get a free prize (physics question)
 

Alright if somebody out there can get this problem you'll win the mystery prize. Don't ask what it is cause its a mystery but its a good prize ;)

Here it is:



What are the horizontal and vertical components of the resultant electrostatic force on the charge in the lower left corner of the square if q = 1.4x10^(-7) Coulombs and a = 5.4 cm? (Assume the positive directions are upward and to the right.)



+q -----a--- (-q)
| |
| |
a a
| |
+2q----a----(-2q)



Hurry up too contest ends tomorrow at 10:00a.m. East coast time

19 ???

BANNED!!! Failure is also punished!!!





j/k :P

Re:Figure this out and you'll get a free prize (physics question)
 

Jello....no wait, ice cream? Wait, what was the question?

"What are the horizontal and vertical components of the resultant electrostatic force on the charge in the lower left corner of the square."


Basically just in vector notation. You gotta use the equation:

F= 8.99x10^9 * (|q1||q2|)/ r^2 where

The q's are the electrical charge. I'll be shittin' kittens if I don't figure this one out.

If that's seriously a question, I'm fucked. I can't follow the first few.....words? Good thing I don't have to know that ---- in my line of work. :-[ :-\

On second thought, with all the fucked up ---- strolling through my mind at odd intervals, I don't want or need any of that ---- taking up space. :-\ I can only imagine the shitty dreams that go along with knowing that sort of thing. ???

---- im chilling here at RPI. I'll see if I can get someone to figure it out for you tomarrow AM. All the fuckers went out clubbing but its all saugage fest BS around here so i just chilled here and watched the pats game with some cool brews.

Re:Figure this out and you'll get a free prize (physics question)
 

horizontal= -2.844*10^(-6) N
vertical= 7.82*10^(-7) N

Re:Figure this out and you'll get a free prize (physics question)
 

you think so? How'd you do it?

Re:Figure this out and you'll get a free prize (physics question)
 

^^^ I think he's right, tell him what hes won Vanna ;)

Re:Figure this out and you'll get a free prize (physics question)
 

this is ------- basic vector ----. don't make it too complicated. just turn all your information into forces and those forces will of course have directions, making them force vectors, then you just break down your vector going diagonal into horizontal and vetical and add it to your horizontal and vertical vectors. you might want to check my work since it's been 3 or 4 months since I raped the physics ap exam and got a 4, and it's not my ass so I didn't check ----.

Re:Figure this out and you'll get a free prize (physics question)
 

whats he won?

je pistons?

Re:Figure this out and you'll get a free prize (physics question)
 

As much as we think Kyle is a shitfaced kid, deep down something tells me he knows what he's doing. <-That wasn't easy to admit. :D


I have a question too. If some one is known to constantly renig on thier promises, does that make them a re------?

Re:Figure this out and you'll get a free prize (physics question)
 

isnt it ironic that whitey is a re------

Re:Figure this out and you'll get a free prize (physics question)
 

whitey better hook it up with something, we've all seen his house so we know he's rich.

steve, although I'm ghetto fabulous I could figure out an equation to solve half the ---- I half ass the correct way, kinda crazy. maybe not, but give me a few years and I could.

Re:Figure this out and you'll get a free prize (physics question)
 

I'm just going to pretend that you guys aren't really talking about a real life problem and continue my simple life in the human world. Thank you. :)

doc, what if a terrorist held you hostage and said he would kill you if you didn't figure that out? you'd be dead, haha.

Re:Figure this out and you'll get a free prize (physics question)
 

Hell no. I'd kill that mother fucker before he ever got the chance. You don't think I watch the ragheads closely? The neighbors across the street have some raghead friends that come to visit from time to time. It's strange because the ragheads are in there earlyto mid thirties and the people are old as ----. I always watch to see what they bring into the house. He tries to nod at me like we're cool or something. ???

wow, you're a hater just for the sake of hating. I don't hate people until they give me a reason to, someone of their race bringing death to my country is not a reason for me to hate someone.

Re:Figure this out and you'll get a free prize (physics question)
 

how are you summing the y direction?

I'm getting:


1.4e(-7)-1.4e(-7)sin45= 1.2e(-8)



Its been a long time since I've done vectors so bare with me

Re:Figure this out and you'll get a free prize (physics question)
 

I might have fucked that side up, like I said, I didn't check it.

Re:Figure this out and you'll get a free prize (physics question)
 

well than how did you get those numbers? in teh vertical theres only the 1.4e(-7) directed up (cause its positive) and the other 1.4e(-7) force directed downward at a 45 off of the y axis...


and in the x direction all I can see is the 45 degree 1.4e(-7) force becuase the other 2 are equal and opposite which cancel each other

Re:Figure this out and you'll get a free prize (physics question)
 

you shouldn't come up with any equal/opposite forces, they're all different forces, are you being sure to note that the distance between +2q and -q is 7.64cm?

Re:Figure this out and you'll get a free prize (physics question)
 

With vectors distances don't matter, I thought the distances of the forces only mattered when finding the moment.

Re:Figure this out and you'll get a free prize (physics question)
 

moment? wtf is that?

all I know is that the vector on the y is 1.2*10^(-6) the one on the x is -2.417*10^(-6) and the 45degree one is .604*10^(-6)

Re:Figure this out and you'll get a free prize (physics question)
 

The moment of rotation of an object. You never did moment equations? In vector calculation the locations that the forces act on the body is not important, its only the direction.

Re:Figure this out and you'll get a free prize (physics question)
 

I did the non calculus physics, we didn't hear about moment, unless I wasn't paying attention for that part.

Re:Figure this out and you'll get a free prize (physics question)
 

When you start engineering classes your going to hear lots about moments. Its the rotating force that the vectors cause on a body. They're actually pretty simple if your good with vectors

Re:Figure this out and you'll get a free prize (physics question)
 

I'm getting a kick out of this thread. Oh ----......

I do alright with vectors. I start engineering classes next semester, I was supposed to go into math 115, that's algebra, but I took a review course and then tested into 191, calc 1.

Re:Figure this out and you'll get a free prize (physics question)
 

yeah dude ---- algebra. They said I had to take pre-calc back in the day and I told them to ---- off and took alot of arguing but I didn't have to take it. I said "I'm paying the money, I'm not wasting my time with pre-calc so just let me in calc and if I fail its my fault"

Re:Figure this out and you'll get a free prize (physics question)
 

I'm gonna quote Whitey and Kyle in this thread and make the directions on how to tune "my new rom editor" for non OBD cars. 8)

hilary duff should let me in her muff.

just call me

Re:Figure this out and you'll get a free prize (physics question)
 

me and kyle are on the same page

Re:Figure this out and you'll get a free prize (physics question)
 

gees just by reading these "answers"drive me crazy.. :P

Re:Figure this out and you'll get a free prize (physics question)
 

anyone who can figure something like this out does not deserve to be banned ;)

By the way I think the answers are:
284N horizontal
-.0781 vertical

Re:Figure this out and you'll get a free prize (physics question)
 

cal 1 is fun kyle, just remember formulas and you will be fine.


what you have to remember in this situation is that they are polar coordinates at first, until you add the +/-2q turning them into cartesian coordinates (the have a magnitude.

Vx^ V
| /Vr
| /
|/_No _>
Vy


so Vx=|V| cosNo
Vy=|V| sinNo
r= square root of (x2+y2)

the easy thing to forget to do in the equasion is the -r

kyle very much surprises me. good on ya mate.

BTW whitey, what is this for in the first place?

Re:Figure this out and you'll get a free prize (physics question)
 

Bamboo, don't tell me you know this ---- too. :o
