Question

Assertion: Frictional force are conservative forces.
Reason: Potential energy change can be assorciated with frictional forces.
A. If both assertion and reason are true and reason is a true explanation of assertion.
B. If both assertion and reason are true but reason is not the correct explanation of assertion.
C. If assertion is true but reason is false.
D. If both assertion is and reason are false.

Answer 1

A field of force such thet the work done on by a body so that it is displaced in the field is independent of the path. Hence, if a body is moved in a closed path the net work done is zero . Gravity and an electrostatic field in vecuum are conservative but any form friction pervent the field from being conservative Also energy connot be assciated with frictional forces
