If a satellite of mass $400 \, kg$ revolves around the earth in an orbit with speed $200 \, m/s$,then its potential energy is .......... $MJ$.

$A$ satellite of mass $m$,initially at rest on the Earth,is launched into a circular orbit at a height equal to the radius of the Earth. The minimum energy required is

$A$ launching vehicle carrying an artificial satellite of mass $m$ is set for launch on the surface of the earth of mass $M$ and radius $R$. If the satellite is intended to move in a circular orbit of radius $7R$,the minimum energy required to be spent by the launching vehicle on the satellite is ($G$ is the gravitational constant).

For a satellite orbiting around the earth in a circular orbit,the ratio of potential energy to kinetic energy at the same height is

Let the kinetic energy of a satellite be $x$,then its time of revolution $T$ is proportional to ..............

An artificial satellite moves in a circular orbit around the earth. The total energy of the satellite is given by $E$. The potential energy of the satellite is
