1.	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
Answer» F = Mg `F = mu Mg` `Mg LE F le Mg sqrt(1+mu^(2))` `Mg ge F ge Mg sqrt(1-mu^(2))` ANSWER :C
