A body of mass 400 g slides on a rough horizontal surface. If the frictional force is 3.0 N, find
(i) the angle made by the contact force on the body with the vertical and
(ii) the magnitude of the contact force. Take `g=10 ms^(-2)`.

Text Solution

Verified by Experts


For vertical equilibrium
`N=Mg=4 N`
`(i) tantheta=3/4`
(ii)F=5N
