    The time period of artificial satellite in a circular orbit of radius R is T. The radius of the orbit in which time period is 8T is:

    A)  2R                  

    B)  3R

    C)  4R                  

    D)  5R

    Correct Answer: C

    Solution :

    As time period    \[T\alpha \,{{R}^{3}}={{\left( \frac{{{T}_{1}}}{{{T}_{2}}} \right)}^{2}}{{\left( \frac{{{R}_{1}}}{{{R}_{2}}} \right)}^{3}}\] \[{{\left( \frac{T}{8T} \right)}^{2}}={{\left( \frac{R}{R} \right)}^{3}}\] \[R'=4R\]
