1. An experiment is run to determine the validity of numerous electrostatic principles. A small ball of mass 6.50 x 10

a. Determine the sign of the charge on each of the plates and the small ball.

b. Draw a free body diagram for the small ball.

c. Determine the magnitude of the electric field produced by the parallel plate capacitor.

d. Solve for the potential difference between the two plates that are separated by a distance of 1.00 x 10

e. A charge of 10.0 C is stored on each plat. Determine the surface area of each plate.

f. Calculate the amount of flux that passes through one plate.

g. Discuss the change in the angle of θ if the same experiment were immersed in non-conductive oil. (Assume the dielectric constant for the oil is greater than that of air.)

I am having a lot of trouble trying to figure out what to do.

So far, for (a) I have the signs as + ---------> -

+ ---------> - etc.

For (b) I have weight going down, the Electric Force, F

For (c) I set Fy = W, and so Fy = 6.37 x 10

This is where I'm stuck, I don't really know how to find the value for the E field. Any help would be much appreciated.

^{-3}kg with a charge of ±1.50 μC is suspended from a non-conductive wire and hangs between two parallel plate capacitors. An angle of 30.0° is measured between the wire and the vertical while the ball is in equilibrium.a. Determine the sign of the charge on each of the plates and the small ball.

b. Draw a free body diagram for the small ball.

c. Determine the magnitude of the electric field produced by the parallel plate capacitor.

_{E}going right, and Tension going North/West at 30°.For (c) I set Fy = W, and so Fy = 6.37 x 10

^{-2}N. Then using trig I found that Fx = 3.68 x 10^{-2}N, which is then equal to the Force.This is where I'm stuck, I don't really know how to find the value for the E field. Any help would be much appreciated.
