Questions
A body of mass M is kept on a rough horizontal surface (friction coefficient ). 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
detailed solution
Correct option is C
Maximum force by surface when friction works F=f2+R2=(μR)2+R2=Rμ2+1Minimum force when there is no friction Hence ranging from R to Rμ2+1We get, Mg≤F≤Mgμ2+1Talk to our academic expert!
