If a 10 charge exists at the centre of a square, the work done in moving a 2 point charge from corner A to corner B of a square ABCD is (a) Zero (b) 5 (c) 2 (d) 20

Answer: (a). A and B are equidistant from the centre charge, so VA = VB. W = q(VB - VA) = 0 So the answer is (a) zero.

If a $10\ \mu\text{C}$ charge exists at the centre of a square, the work done in moving a $2\ \mu\text{C}$ point charge from corner A to corner B of a square ABCD is

Show answer and solution

Answer: (a)

A and B are equidistant from the centre charge, so $V_A = V_B$ .
$W = q(V_B - V_A) = 0$
So the answer is (a) zero.
