Two homogeneous spherical balls rest between two vertical walls as shown in figure. The radius
of smaller ball is 16 cm and weight is 1.15 kN. The radius of the larger ball is 24 cm and its
weight is 3.45 kN. The distance between the walls is 72cm. Assuming the contact surfaces to be
smooth, (a) Draw the free body diagram of two balls (b)
