$A$ satellite of mass $m$ revolving in a circular orbit of radius $r$ around the Earth has kinetic energy $E$. Then its angular momentum will be

Two identical satellites are at heights $R$ and $7R$ from the Earth's surface. Which of the following statements is incorrect? ($R =$ radius of the Earth)

An artificial satellite moving in a circular orbit at a distance $h$ from the centre of the Earth has a total energy $E_0$. Then,its potential energy is

For a satellite moving in an orbit around the earth,the ratio of kinetic energy to potential energy is

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

$A$ satellite of mass $m$ is in a circular orbit of radius $2R_E$ around the Earth. The energy required to transfer it to a circular orbit of radius $4R_E$ is (where $M_E$ and $R_E$ are the mass and radius of the Earth,respectively).
