a) A book, of weight 8 N, rests in equilibrium on a desk top inclined at 28 degrees to the horizontal. Find the frictional force acting on the book.
b) The coefficient of friction between the book and the desk top is 0.6. Determine whether the equilibrium is limiting.
Please explain so that I can understand =)
