The work done in moving a charge of 1C between two points on an equipotential surface is
1 J
9 × 10-9 J
Zero
1.6 × 10-19 J
There is no potential difference between any two points on the equipotential surface and no work is required to move a test charge on the surface.
The amount of work done in moving a unit positive charge through distance of 10 cm on an equipotential surface is
