16. As shown in the figure, the smooth surface of the ball A has a radius of 10 cm. It is hung on a vertical wall with a hanging line of length L=50 cm. Object B is sandwiched between the ball and the wall. It is 20 cm thick and weighs 12 N. The coefficient of kinetic friction between B and the wall is u=0.2. The block B slides down the wall evenly without leaving the ball A. (1) the gravity of the ball A; (2) The pressure of the ball A on block B. L
