Problem
A block of mass 5kg is kept at rest on a smooth plane inclined at 25∘ to the horizontal. A force P is applied parallel to the plane and directed up the incline so that the block stays at rest.
(i) Calculate the magnitude of the applied force P.
(ii) Determine the magnitude of the normal reaction exerted by the plane on the block.
