A charge of 10 p. C lies at the centre of a square. Work done in carrying a charge of 2 p C from one comer of square to the diagonally opposite comer is
Since the charge is at the center of the square, the potential at all corners is the same. Moving a charge between two points at the same potential requires no work because the potential difference is zero.
Thus, the correct answer is (c) Zero.

The correct answer is (c) Zero.
The work done in moving a charge in an electric field is given by W = qΔV. Since the charge is at the center of the square, all corners are at the same potential. The potential difference (ΔV) between diagonally opposite corners is zero, making the work done also zero, regardless of the path taken.
