Question

Which of the following is a non-conservative force? (A) electrostatic force (B) viscous force (C) interatomic force (D) gravitational force

Tardigrade Admin · Accepted Answer

Electrostatic force, gravitational force and spring force are the conservative forces because the workdone by these forces is path independent whereas viscous force is a non-conservative force as the work done by this force is path dependent.
