A body of mass 2kg lies on a rough plane which is inclined at 30^{o} to the horizontal. A horizontal force of 20N is applied to the body in an attempt to push it up the plane, the body is found to be on the point of moving up the plane. Find μ, the coefficient of friction, between the body and the plane.

The answer is 0.279. Any help is greatly appreciated!
