    Which of the following graphs shows the variation of electric field E due to a hollow spherical conductor of radius R as a function of distance from the centre of the sphere [AMU 2001]

    A)           

    B)                                                 

    C)                             

    D)           

    Correct Answer: A

    Solution :

               Electric field due to a hollow spherical conductor is governed by following equation \[E=0,\] for r < R ...(i) and \[E=\frac{Q}{4\pi {{\varepsilon }_{0}}{{r}^{2}}}\]  for \[r\ge R\] ....(ii) i.e. inside the conductor field will be zero and outside the conductor will vary according to \[E\propto \frac{1}{{{r}^{2}}}\]
