If a unit positive charge is taken from one point to another over an equipotential surface, then
If a unit positive charge is taken from one point to another over an equipotential surface, then
work is done on the charge
work is done by the charge
work done is constant
no work is done
Solution
Potential difference between any two points on equipotential surface is zero. i.e.,
\(V_1-V_2=0\)
\(\therefore\) Work done to move a unit positive charge from one point another,
\(W=q\left(V_1-V_2\right)=q[0]=0\)
