Electric potential by charge 500 μC at the diagonally opposite points on the square is same.
So the potential difference is zero between the diagonally opposite points on the square.
Work done = Potential difference x charge = zero

The 500 μC charge is at the same distance from all the corners of the square. The opposite corners, say A and C, will have the same potential VA = VC
Work done in moving a charge q between points A and C is given as:
W = q(VC - VA) = q × 0 = 0
Hence, no work is done in moving the charge between two diagonally opposite points on the square.
Work done in moving a charge q between points A and C is given as:
W = q(VC - VA) = q × 0 = 0
Hence, no work is done in moving the charge between two diagonally opposite points on the square.
