List of top Physics Questions on Gravitation asked in Rajasthan PMT

Acceleration due to gravity at earth's surface is $g \,ms ^{-2}$. Find the effective value of gravity at a height of $32\, km$ from sea level $:\left(R_{e}=6400 \,km \right)$

Near earths surface, time period of a satellite is $4 h$. Find its time period at height $4R$ from the centre of earth :

Assuming earth to be sphere of uniform density what is the value of acceleration due to gravity at a point $100\, km$ below the earth surface (Given $R=6380\,\times 10^{3}\,m$)

The weight of an object at earth's surface is $700\, g\, wt$. What will be its weight at the surface of a planet whose radius is $1 / 2$ and mass is $1 / 7$ of that of the earth ?

Reason for weightlessness in satellite:

A satellite of mass $ m_{s} $ is moving in an orbit of radius $R$, then its angular momentum:

The ratio of escape velocity and orbital velocity of satellite revolving near the earth:

The relation between time period $(T)$ of a body and radius of circular orbit $(r)$ is:
