    In a hollow spherical shell potential (V) changes with respect to distance (r) from centre                                               [DCE 2001, 03]

    A)                  

    B)                            

    C)                      

    D)           

    Correct Answer: B

    Solution :

                       \[{{V}_{inside}}=\frac{Q}{4\pi {{\varepsilon }_{0}}R}\]   for \[r\le R\]    ....(i) and \[{{V}_{out}}=\frac{Q}{4\pi {{\varepsilon }_{0}}r}\]  for \[r\ge R\]   ....(ii) i.e. potential inside the hollow spherical shell is constant and outside varies according to \[V\propto \frac{1}{r}\].
