20. The free-body diagram of the force acting on the plumb line is shown on the right. The mass of the sphere is 33 3 3 3 13 44 (2.6 10 kg/m )(2.00 10 m) 8.71 10 kg. MV R ππ ρρ §· == = × × ¨¸ ©¹ The force between the “spherical” mountain and the plumb line is 2 / FG M m r = . Suppose at equilibrium the line makes an angle θ with the vertical and the net force acting on the line is zero. Therefore,
