S K Sharma Solutions for Chapter: Gravitation, Exercise 3: UNSOLVED NUMERICALS FOR PRACTICE

A body weighs $30 \mathrm{N}$ on the surface of the earth. How much will it weigh on the surface of moon? Given $g_{moon}=\frac{1}{6}\times g_{earth}$.

The mass of a body is $60 \mathrm{kg}$. Find the weight of the body. (Take $g = 9.8 \mathrm{m}/{\mathrm{s}}^2$)

The mass of a body is $40 \mathrm{kg}$. Find the weight of the body on the surface of a planet whose mass is double than the mass of the earth and radius is four times the radius of the earth. (Take $g = 9.8 \mathrm{m}/{\mathrm{s}}^2$)
