Homework Statement Two charges, one of 3.2 x 10 ^ -9 C, the other one of -6.4x10^-9 C are 42 cm apart. Calculate the net electric field at point P, 15 cm from the postie charge, on the line connecting the charges (+) -------------(Point)---------------------- (-) 15cm...

Ok thank you.

Do you know another method to solve for v then? As far as I know, using kinematic and work equations are the only way to get the velocity.

I'm calculating the velocity without any of the friction, since it is too complicated for me to calculate at the moment, the current also saying inbetween 3-3.5 amps while it is moving (I'm only taking the current given off by the battery and the magnets attached to it. (at least for the double...

So would I just use kinematics to solve for v2?

FPull= ( n x I ) 2 μ0(A/(2g)^2) F : Force. n : Number of turns. I : Current. μ0 : permeability of air. A: Area in m2 g : the gap that is separating the electromagnet and the object. I used this equation. N was 18, the number of coils the magnet had "seen" I was the current, around 3.8 amps...

If anyone can help here, I'd greatly appreciate it. This question has been bugging me for the past few days.

Anyone?

I have figured out which equation to use and finding an equation isn't the issue, I have another question about the force calculated. Sorry for bringing this back up, but that initial equation I have used is working, I do get 0.35m/s (which is pretty fast) as a final result. Although, One...

okay haha, thanks.

I just saw your response, and 8 amps for a 1.5v battery? Just double checking, thank you very much.

Ok, say this distance is like 20-25 cm of copper wire. What would the current be? any estimate? FPull= ( n x I )^ 2 * μ0(A/(2g)^2) n would be the number of copper wire coils in between the two magnets i would be measured using the distance of the coils in between the two magnets A would...

Oh, so the amount of current measured would be in a circuit that had a copper wire as long as the number of coils in between the two magnets?

IS there any way to take mass into consideration while calculating for the velocity using this equation?

So let's say I have 200 coils for a 0.4m track, my k value would be 200/0.4 correct?
