Question

Which of the following is a conservative force? 1.force due to friction 2.force due to gravity 3. both (1) and (2) 4. neither (1) nor (2)

Answer 1

Option 2 is the correct answer.

Step-by-step explanation:

I f the work done by a force does not depend upon the path of mass then the force is called conservative force.

Work done by frictional force depends upon path followed by mass, so frictional force is a non conservative force. But work done by gravitational force does not depend upon path followed by mass, so gravitational force is a conservative force.

Option 2 is the correct answer.
