Step 1
Since the square lies in the x-y plane, the electric field due to each corner charge will have a component in the z-direction (upwards) at this point. The electric field due to a point charge at a distance r from the charge is given by Coulomb's Law: E = k * q / Show more…

Four charges are placed at the corners of a square with sides of length 2m. The top two charges have a charge of Q=7.87nC, and the bottom two charges have a charge of -7.87nC. (a) Draw the electric field contribution from each charge and find the electric field vector (magnitude and direction) at the center of the square. (b) Find the electric potential at the center of the square.

1. Find the electric field at the point marked P for the charge distribution shown below: 2. Suppose 4 charges are fixed on the corners of a square, 20 centimeters on a side. The two upper charges are each 1.5 * 10^-7 C and the lower charges are -3.0 * 10^-7 C. Find the electric field at the center of the square.
