A body is placed on the rough inclined plane having inclination θ greater than angle of repose ϕ. What is the force of friction between the body and inclined plane?

Solution

A body placed on the rough inclined plane has angle of inclination greater than angle of repose.
So,
Force of friction between the body and the inclined plane is given by,
f = $space space mg space cosθ space tanϕ.$
