# Magnitude of force the earth exerts on the moon

Using the mass of the earth and moon, try to find the force that the earth exerts on the moon:

The mass of the Earth is me = 5.98 x 1024 kg, and the mass of the Moon is mm = 7.36 x 1022 kg. The average Earth to Moon distance is 3.84 x 108 m. The universal gravitational constant is G = 6.67 x 10-11 Nm2/kg2.

Calculate the magnitude of the force the Earth exerts on the Moon. (Select one.)

a. 7.64 x 1028

b. 1.99 x 1031

c. 1.99 x 1020

d. 3.0 x 1030
