Question

Compare the gravitational attraction on the earth due to the attraction of sun due to attraction of moon. Given mass of sun = 2 x 1039 kg, mass of moon = 7.35 x 1022 kg, distance of sun from earth = 1.5 * 1011 m, distance of moon from earth = 3.84 x 108m.​

Answer 1

Given :       Mass of earth    m=6×1024kg

                   Mass of Sun    M=2×1030kg

                  Distance between sun and earth       r=1.5×1011 m

Force of gravitation between them       F=r2GMm

F=(1.5×1011)26.67×10−11×(6×1024)×(2×1030)=3.557×1022  N
