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
Write the characteristics of equipotential surface.
Assertion : Two equipotential surfaces cannot cut each other.
Reason : Two equipotential surfaces are parallel to each other.
The diagrams below show regions of equipotentials.A positive charge is moved from $A$ to $B$ in each diagram.
Draw an equipotential surface for a point charge.
Draw an equipotential surface for dipole.
