Question
Physics Question on work, energy and power
Which of the following is a non-conservative force?
A
electrostatic force
B
viscous force
C
interatomic force
D
gravitational force
Answer
viscous force
Explanation
Solution
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.
