Question

Both weight and surface area doubled what will happens friction

Answer 1

Explanation:

Doubling the mass will only make the perpendicular contact force become double and have no effect on the coefficient of friction. It DOES NOT depend on the weight of the body…….only the frictional FORCE depends on the weight of the body as F=umg, where u is the coefficient of friction

Answer 2

Explanation:

If the weight of object doubled then the force of friction double and it is not depend upon the surface area increase or decrease.
