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

• A. Least along the path AE
• B. Least along the path AC
• C. Zero along any of the paths
• D. Least along AB

Answer 1

The correct option is C

Zero along any of the paths

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