The Moon's mass is 7.34 x 10^22 kg, and it is 3.8 x 10^8 away from Earth. Earth's mass if 5.97 x 10^24 kg.

a. Calculate the gravitional force of attraction between Earth and the Moon.

b. Find Earth's gravitional field at the moon.

GIVEN:

Moon's mass = 7.34 x 10^22 kg

Earth's mass = 5.97 x 10^24 kg

Would you use g = Fg/m?
