ABCD is a cross-section of a uniform rectangular block of mass 20kg. AB is 0.75m and BC is 1m. The block rests with A on rough horizontal ground with AB at 20 degrees to the horizontal. It is held in place by a horizontal force P N applied at C. Given that the block is on the point of slipping, find the value of P and the coefficient of friction between the block and the ground.
