    The outer sphere of a spherical air capacitor is earthed. For increasing its capacitance                                      [MP PET 1991]

    A)                    Vacuum is created between two spheres

    B)                    Dielectric material is filled between the two spheres

    C)                    The space between two spheres is increased

    D)                    The earthing of the outer sphere is removed

    Correct Answer: B

    Solution :

               In spherical capacitor \[C=4\pi {{\varepsilon }_{0}}K\,\left( \frac{ab}{b-a} \right)\] Þ \[C\propto K\]
