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 the body is $F$, where
  • A$F = Mg$
  • B$F = \mu Mgf$
  • C$Mg \le F \le Mg\sqrt {1 + {\mu ^2}} $
  • D$Mg \ge F \ge Mg\sqrt {1 + {\mu ^2}} $
