$A$ body is projected with a velocity greater than orbital velocity but less than escape velocity. Its path is

The orbital angular momentum of a satellite is $L$,when it is revolving in a circular orbit at height $h$ from the earth's surface. If the distance of the satellite from the earth's centre is increased by eight times its initial value,then the new angular momentum will be $............\,L$.

Given the radius of Earth $R$ and the length of a day $T$,the height of a geostationary satellite is: [$G$ = Gravitational Constant,$M$ = Mass of Earth]

Which force is responsible for the necessary centripetal force of a satellite revolving around the Earth?

Two stars of equal masses $M$ are orbiting in a circle of radius $R$. Their orbital time period is proportional to

$A$ satellite $S$ is moving in an elliptical orbit around the Earth. The mass of the satellite is very small compared to the mass of the Earth.
