We will do this by finding the gravitational field g due to the Moon or the Sun, which is the acceleration that the Earth would have if it were interacting with each of them. 33% Part a Calculate the magnitude of the gravitational field of the moon at the location of au, in meters per square second 33% Part (b) Calculate the magnitude of une gravitational field of the Sun at the location of Earth in meters per square second.

Explanation / Answer

distance of sun from earth=Rsun=149600000000m

distnace of moon from earth=Rmoon=384400000 m

Mmoon=7.35*10^22

Msun=1.98*10^30

(a) For Moon

gmoon=GMmoon/Rmoon^2=3.33*10^(-5) m/s^2

(b)

gsun=GMsun/rsun^2=5.9*10^(-3) m/s^2

(c) ratio=177.208:1
