    Which one of the following plots represents the variation of gravitational field on a particle with distance r due to a thin spherical shell of radius R? (r is measured from the centre of the spherical shell)

    A)

    B)

    C)

    D)

    Correct Answer: B

    Solution :

    [b] The Gravitational field due to a thin spherical shell of radius R at distance r. \[E=\frac{GM}{{{r}^{2}}}\left( \operatorname{If}r>R \right)\] For r=R i.e. on the surface of the shell \[E=\frac{GM}{{{R}^{2}}}\] For \[r<R\]i.e. inside the shell \[E=0\]
