6. The moon's mass is 7.35 x 10" kg, and it moves around the earth approximately in a circle of radius, r= 3.82 x 10 m. The time required for one revolution is 27.3 days (convert to seconds). a. Calculate the net centripetal force, EF. , that must act on the moon. (EF, = my=/r) b. How does this value compare to the gravitational force value calculated using the Newton's Universal Law of Gravitation that the earth exerts on the moon at that same distance? (M.... = 6 x 10- kg. G = 6.67 x 10 2 Nm=/kgz)
