Exercise 2.7
The mass of the moon is \displaystyle \text{7}.\text{38}\times \text{1}{{0}^{\text{22}}}\text{kg} and the radius of the moon is \displaystyle \text{1}.\text{73}\times \text{1}{{0}^{\text{6}}}\text{m} . Determine the acceleration due to gravity on the moon, by considering the force that the moon exerts on a particle of mass \displaystyle \text{1 kg} . on its surface.
