    If M is the mass of the earth and R its radius, the ratio of the gravitational acceleration   and   the   gravitational constant is:

    A)  \[\frac{{{R}^{2}}}{M}\]                                

    B)  \[\frac{M}{{{R}^{2}}}\]

    C)  \[M{{R}^{2}}\]                                 

    D)  \[\frac{M}{R}\]

    Correct Answer: B

    Solution :

    Gravitational acceleration is given by                 \[g=\frac{GM}{{{R}^{2}}}\] where G = gravitational constant \[\therefore \]  \[\frac{g}{G}=\frac{M}{{{R}^{2}}}\]
