JEE Main & Advanced Physics Electrostatics & Capacitance Question Bank Electric Field and Potential

  • question_answer
    The potential at a distance R/2 from the centre of a conducting sphere of radius R will be              [RPMT 2003]

    A)                    0                                        

    B)            \[\frac{Q}{8\pi {{\varepsilon }_{0}}R}\]

    C)                       \[\frac{Q}{4\pi {{\varepsilon }_{0}}R}\]

    D)            \[\frac{Q}{2\pi {{\varepsilon }_{0}}R}\]

    Correct Answer: C

    Solution :

                 Potential inside the conducting sphere is same as that of surface i.e. \[\frac{Q}{4\pi {{\varepsilon }_{0}}R}\]
