The Force Exerted on the Moon (Figure 1)shows the Earth, Moon, and Sun (not to scale) in their relative positions at the time when the Moon is in its third-quarter phase.

Though few people realize it, the force exerted on the Moon by the Sun is actually greater than the force exerted on the Moon by the Earth. In fact, the force exerted on the Moon by the Sun has a magnitude of FSM=4.34×1020N, whereas the force exerted by the Earth has a magnitude of only FEM=1.98×1020N. These forces are indicated to scale in the figure.


a- Find the direction of the net force acting on the Moon

b- Find the magnitude of the net force acting on the Moon
