        The time period of an earth satellite in circular orbit is independent of

    A)  the mass of the satellite

    B)  radius of its orbit

    C)  both the mass and radius of the orbit

    D)  neither the mass of the satellite nor the radius of its orbit

    Correct Answer: A

    Solution :

                    Time period of satellite \[T=2\pi \sqrt{\frac{{{(R+h)}^{3}}}{G{{M}_{e}}}}\] where\[R+h=\]orbital radius of satellite, \[{{M}_{e}}=\]mass of earth Thus, time period does not depend on mass of satellite.
