  • question_answer
    If Gravitational constant is decreasing in time, what will remain unchanged in case of a satellite orbiting around earth                       [DCE 1999, 2001]

    A) Time period

    B)               Orbiting radius

    C)             Tangential velocity      

    D)             Angular velocity

    Correct Answer: C

    Solution :

                    \[{{T}^{2}}=\frac{4{{\pi }^{2}}}{GM}{{r}^{3}}\]. If G is variable then time period, angular velocity and orbital radius also changes accordingly.
