A block of mass 5 kg rests on a rough plane inclined at 30∘ 30^\circ\,30∘ to the horizontal. The coefficient of friction is 0.2. A force of magnitude P P\,P N acts up a line of greatest slope. Take g=9.8g=9.8g=9.8 m s−2^{-2}−2.
Find the range of values of P P\,P for which the block remains in equilibrium.
