The sun’s mass is about 3.2 x 10^5 times the earth’s mass. The sun is about 400 times as far from the earth as the earth is from the moon. Assume that the sun – moon distance is constant and equal to sun – earth distance. The ratio of the magni9tudes of the gravitational pull of the sun on the moon ( Fms ) and of the earth on the moon ( Fem ) will be Fms/ Fme = ‘*’. Find ‘*’.
