Question

four equal charges q are placed at the four corners of a square of each side is a. work done in moving a charge​

Answer 1

Answer:

At the center of the square as a result of the four equal charges q at the corners, potential(V) will be . As, the sides are a thus the diagonals will be of length a√2, so both of the diagonals will be 2*a√2. By using the formulae, V=4q/4πε0(a√2)2=√2qπε0a. Since, work done from center O to infinity W0∞=−W∞0.
