If a unit positive charge is taken from one point to another over an equipotential surface, then

Options

  1. Awork is done on the charge
  2. Bwork is done by the charge
  3. Cwork done is constant
  4. Dno work is done

Correct answer

D. no work is done

Step-by-step solution

Potential difference between any two points on equipotential surface is zero. i.e., (V₁-V₂=0 ) ( ) Work done to move a unit positive charge from one point another, (W=q (V₁-V₂ )=q[0]=0 )
