The ratio of inertial mass and gravitational mass has been found to be $1$ for all material bodies. Were this ratio different for different bodies, the two bodies having same gravitational mass but different inertial mass would have?

How much radius of earth at equator is grater than the radius at poles of earth ?

At what height above the surface of earth the value of $"g"$ decreases by $2 \%$ ….. $km$ [radius of the earth is $6400 \,km$ ]

A $90 \mathrm{~kg}$ body placed at $2 \mathrm{R}$ distance from surface of earth experiences gravitational pull of : ( $\mathrm{R}=$ Radius of earth, $\mathrm{g}=10 \mathrm{~ms}^{-2}$ )

Acceleration due to gravity $'g'$ for a body of mass $'m'$ on earth's surface is proportional to (Radius of earth$=R$, mass of earth$=M$)
