Two parallel, thin, L×L�×� conducting plates are separated by a distance d�, as shown. Let L=�=2.5 m, and d=�=2.0 mm. A charge of ++6.5μC�C is placed on one plate, and a charge of −−6.5μC�C is placed on the other plate. a) What is the magnitude of charge density on the inside surfae of each plate in Coulombs per squae meter? b) What is the magnitude of the electric field between the plates? I was able to find the charge density easily. I am not certain about the electric field.
The surface charge density (eta) h of an infinite charged plane is -2.0 x 10-6 C/m2. A proton is shot straight away from the plane at 2.0 x 106 m/s. Make a sketch of the situation. How far does the proton travel before reaching its turning point?
Three charged marbles are glued to a nonconducting surface and are placed in the diagram as shown. The charges of each marble are q1 = 6.20 µC, q2 = 1.43 µC, and q3 = −2.01 µC. Marble q1 is a distance r1 = 3.00 cm to the left of the marble q2, while marble q3 is a distance r3 = 2.00 cm to the right of the marble q2. Calculate the magnitude of the electric field a distance r' = 1.00 cm to the left of the center marble.N/C Another marble is placed 1 cm to the left of the middle marble. If this new marble has a charge of 3.62 µC, calculate the magnitude and direction of the force on it.

A non-conductive plate (thick slice) has a thickness of 2d, which is small compared to its height and width. The origin is in the center of this plate (slice) and the x-axis is along the thickness of this plate. This plate has volumetric charge densities where p (x) = -P in the region where -d <x <0, where po is a positive constant, and p (x) = + Po in the region where 0 <x <+ d. What happens to the electrified vector in the region where x = d / 3?

A 0.01294 kg ball with a positive charge of 47.4 μC hangs from a light string right next to a large vertical metal plate (the metal plate is so large compared to the length of the string and ball consider it to be infinite in size). How much surface charge density must the plate have to repel the ball so that the string makes and angle of 5.03 degrees from the vertical. Give your answer to 3 significant figures and in units of nC/m/m (nanoCoulombs per meter squared: Blackboard has trouble with squred units). Type in the units right after your numerical answer.
A conducting sphere of radius r1 = 0.46 m has a total charge of Q = 2.9 μC. A second uncharged conducting sphere of radius r2 = 0.23 m is then connected to the first by a thin conducting wire.
