Radius of orbit of satellite of earth is `R`. Its kinetic energy is proportional to

The radius of the orbit of a satellite is r and its kinetic energy is k if the radius of the orbit is doubled then the new kinetic energy k is

The time period of a satellite in a circular orbit around the earth is T . The kinetic energy of the satellite is proportional to T^(-n) . Then, n is equal to :

The time period of a satellite in a circular orbit around the earth is T . The kinetic energy of the satellite is proportional to T^(-n) . Then, n is equal to :

If radius of an orbitating satellite is decreased , then its kinetic energy

If radius of an orbitating satellite is decreased , then its kinetic energy

A satellite is in an orbit around the earth. If its kinetic energy is doubled, then it will:
