Vedclass · Answer

(B) The orbital velocity of a satellite is given by $V_0 = \sqrt{\frac{GM}{r}}$. Since both satellites are in the same orbit,they have the same orbital radius $r$. Thus,both move with the same speed.Potential energy is given by $U = -\frac{GM_e m}{r}$. Since the masses $m$ of the satellites are different,their potential energies are different.Kinetic energy is given by $K = \frac{1}{2}mv^2$. Since the masses are different,their kinetic energies are different.The time period is given by $T = 2\pi \sqrt{\frac{r^3}{GM}}$. Since $r$ is the same for both,their time periods are equal.Therefore,the statement that $S_1$ and $S_2$ are moving with the same speed is true.

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?
