The work done to move a charge on an equivalent surface is

Options

  1. AInfinity
  2. BLess than ( 1 )
  3. CGreater than ( 1 )
  4. DZero

Correct answer

D. Zero

Step-by-step solution

An equipotential surface has same electric potential at all points. Therefore, work done in moving a charge on an equipotential surface is [ array l W=q (V_ B -V_ A ) But V_ A =V_ B W=0 array ] Therefore, work done in moving a charge on an equipotential surface is zero.
