Solution

The correct option is D
Electron

An electric current is the rate of flow of charge per unit time. The movement of electrons in a wire constitutes the electric current. Protons and neutrons are situated inside the nucleus of an atom. The moving charged particles in electric current are called charge carriers.

Q. A proton is kept at rest. A positively charged particle is released from rest at a distance d in its field. Consider two experiments; one in which the charged particle is also a proton and in another, a positron. In the same time t, the work done on the two moving charged particles is (a) same as the same force law is involved in the two experiments. (b) less for the case of a positron, as the positron moves away more rapidly and the force on it weakens. (c) more for the case of a positron, as the positron moves away a larger distance.
