1.	Two satellites of earth S_(1)andS_(2) are moving in the same orbit. If the mass of S_(1) is four times the mass of S_(2) then which one of the following statements is true?
Answer» The potential energies of EARTH and satellite in both cases are equal. The KINETIC energies of two SATELLITES are equal. The time PERIOD of `S_(1)` is four times the time period of `S_(2)`. Satellites `S_(1)andS_(2)` are MOVING with same speed. Solution :Since speed of a satellite is independent of its mass.
