Question
A point charge q is held at the centre of a circle of radius r. B, C are two points on the circumference of the circle and A is a point outside the circle. If WAB represents work done by electric field in taking a charge q0 from A to B and WAC represents the workdone from A to C, then (1) WAB > WAC (2) WAB < WAC (3) WAB = WAC ≠0 (4) WAB = WAC = 0
