Q75 / 75 · JEE Main 2025 (7 Apr Shift 2) · Physics

Which one of the following forces cannot be expressed in terms of potential energy?

A
Coulomb's force
B
Gravitational force
Correct answer
C
Frictional force
D
Restoring force

Solution

Potential energy is defined for conservative force only. It is not defined for non-conservative force i.e. frictional force.

Hence, the correct answer is option: 'C'.
