A block of mass 70kg is kept on a rough horizontal surface `(mu=0.4)` . A person is trying to pull the block by applying a horizontal force, but the block is not moving. The net contact force exerted by the surface on the block is `F` , then:

A body of mass M is kept on a rough horizontal surface (friction coefficient = mu .). A person is trying to pull the body by applying a horizontal force but the body is not moving. The force by the surface on A is F where

A body of mass M is kept on a rough horizontal surface (friction coefficient =μ). A person is trying to pull the body by applying a horizontal force but the body is not moving. The force by the horizontal surface on the surface of the body is F, where
