Question

Statement 1 : No work is required to be done to move a test charge between any two points on an equipotential surface. Statement 2 : Electric lines of force at the equipotential surfaces are mutually perpendicular to each other.

TestHub · Accepted Answer

Statement 1 is true: on an equipotential surface $Δ V = 0$ , so the work $W = q Δ V = 0$ .

Statement 2 is true (intended reading): electric field lines are everywhere perpendicular to equipotential surfaces.

Since the force on the charge is perpendicular to any displacement along the surface, no work is done - Statement 2 correctly explains Statement 1. Option (A).
