1.	Two satellites of earth. S_(1)" and "S_(2) are moving in the same orbit. The mass of S_1 is four times the mass of S_2. Which one of the following statements is true?
Answer» the potential energies of earth satellites in the two cases are EQUAL. `S_(1)" and "S_(2)` are MOVING with the same speed The kinetic energies of the two satellites are equal The TIEM PERIOD of `S_(1)` is four times that of `S_(2)`. ANSWER :B
