Question

In the electric field of a point charge q, a certain point charge is carried from point A to B, C, D and E as shown in figure. The work done is

  1. least along the path AE
  2. least along the path AC
  3. zero along any of the paths
  4. least along AB

The correct answer is: zero along any of the paths


    . For charge q placed at the centre of circle, the circular path is an equipotential surface and hence work done along all paths AB or AC or AD or AE is zero
