(c) When two satellite of earth are moving in same orbit, then time period of both are equal. From Kepler’s third law
Time period is independent of mass, hence their time periods will be equal. The potential energy and kinetic energy are mass dependent, hence the PE and KE of satellites are not equal. But, if they are orbiting in a same orbit, then they have equal orbital speed. |
