Two satellites of earth, S1 and S2 are moving in the same orbit. The mass of S1 is four times the mass of S2 . Which one of the following statements is true? |
The potential energies of earth satellites in the two cases are equal. S1 and S2 are moving with the same speed. The kinetic energies of the two satellites are equal. The time period of S1 is four times that of S2 . |
S1 and S2 are moving with the same speed. |
Since orbital velocity of satellite is \(v = \sqrt{\frac{GM}{r}}\), it does not depend upon the mass of the satellite. Therefore, both satellites will move with same speed. |
