Can someone solve this question ?
A package of mass 4kg lies on a rough plane inclined at 30 degrees to the horizontal. The package is held in equilibrium by a force of magnitude 45N acting at an angle of 50 degrees to the plane. The force is acting in a vertical plane through a line of greatest slope of the plane. The package is in equilibrium on the point of moving up the plane.
