    A satellite of mass m goes round the earth along a circular path of radius r, let Mg is the mass of the earth and Rg its radius. Then the linear speed of the satellite depends

    A)  \[{{M}_{e}}\]                                   

    B)  \[{{M}_{e}}\] only

    C) \[\mu ,{{\mu }_{e}},V\]                               

    D)  \[{{M}_{e}},{{R}_{e}}\]and \[r\]

    Correct Answer: D

    Solution :

                     Orbital velocity \[({{v}_{0}})\] of a satellite orbiting in a circular orbit of radius r is given by                 \[{{v}_{0}}=\sqrt{\frac{G{{M}_{e}}}{r}}\] Hence, orbital velocity depends on \[{{M}_{e}},\,{{R}_{e}}\] and r.
