Chhattisgarh Board Solutions for Chapter: Gravitation, Exercise 2: Question

Mass of the moon is $M_{\mathrm{moon}}=7\times {10}^{22} \mathrm{kg}$ and its radius is $R_{\mathrm{moon}}=1700 \mathrm{km}$. Find out the value of acceleration on the surface of moon for an object of mass $\text{'}m\text{'}$. $(G=6.67\times {10}^{-11} \mathrm{N} {\mathrm{m}}^2 {\mathrm{kg}}^{-2})$

Compare the weight of an object of mass $\text{'}m\text{'}$ on the surface of earth and the moon.

Mass of the earth and moon is $6\times {10}^{24} \mathrm{kg}$  and  $7\times {10}^{22} \mathrm{kg}$ respectively. The distance between the centers of earth and the moon is $3.84\times {10}^5 \mathrm{km}$. How much force will they exert on each other?
