Question

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

• A. Work is done on the charge
• B. Work is done by the charge
• C. Work done is constant
• D. No work is done

Answer 1

The correct option is D No work is done

On the equipotential surface, electric field is normal to the charged surface (where potential exists) so no work will be done.
