Question

Work done to bring a unit positive charge from infinity to a point in an electric field is known as _______

(a) Electric potential

(b) Electric field intensity

(c) Electric dipole moment

(d) The total energy of the point charge

The question was posed to me during an interview.

My doubt is from Electrostatic Potential topic in section Electrostatic Potential and Capacitance of Physics – Class 12

Answer 1

Correct choice is (a) Electric potential

Easy explanation: Electric potential is defined as the amount of work done to bring a unit positive charge from an infinite distance to a particular point of an electric field. The total energy of that point charge means the sum of kinetic energy and potential energy which is not the same as the potential energy if the particle is in motion.
