Question

The factors on which coefficient of friction depends is: a) Weight of the body b) Surface area in contact c) Nature of surface in contact d) None of these​

Answer 1

Answer

Option C

Explanation:

The coefficient of friction depends on the nature of the surface in contact. The coefficient of friction is the ratio of frictional force to the normal force acting on the same body. It is a dimensionless quantity. Unlike frictional force, this quantity has no dependence on surface area or other factors except the nature of the surface in contact.
