Question
Assertion & Reason type
Statement1: Electric field is always perpendicular to an equipotential surface.
Statement2: If there was a component of →E along the surface, that would mean there is a potential change along that component and hence the surface is not equipotential.

Solution
The correct option is A Statement 1 is correct, statement 2 is correct and statement 2 is the correct reason for assertive statement 1.
From its name itself it is clear that the potential has to be constant throughout the equipotential surface. Now if potential is not varying then there cannot be an electric field along the equipotential surface and hence has to be normal to it.
It just implies that if there would have been any field along the surface then the potential gradient wouldn’t be zero and charges would move.
