    The time period of an artificial satellite in a circular orbit is independent of

    A)  the mass of the satellite

    B)  radius of the orbit

    C)  mass of the earth and radius of the earth

    D)  None of the above

    Correct Answer: A

    Solution :

    The time period of an artificial satellite is given by \[T=2\pi \sqrt{\frac{{{({{R}_{e}}+h)}^{3}}}{gR_{e}^{2}}}\] where \[{{R}_{e}}\] is radius of earth and h the height of satellite. From the above formula it is clear that time period of revolution does not depend upon the mass of the satellite.
