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 surface on the body is F where
- F = Mg
- F = Mg
- \(M g \leq F \leq M g \sqrt{1+\mu^{2}}\)
- \(M g \geq F \geq M g \sqrt{1-\mu^{2}}\)
Answer
(C) M g F M g 1+ ^ 2
