JEE Main & Advanced Physics Electrostatics & Capacitance Question Bank Charge and Coulombs Law

  • question_answer
    When \[{{10}^{14}}\] electrons are removed from a neutral metal sphere, the charge on the sphere becomes                                                                                     [Manipal JEE 1995]           

    A)                    \[16\,\mu \,C\]

    B)                    \[-16\,\mu \,C\]

    C)                    \[32\,\mu \,C\]           

    D)                    \[-32\,\mu \,C\]

    Correct Answer: A

    Solution :

                                 \[Q=ne={{10}^{14}}\times 1.6\times {{10}^{-19}}\]Þ \[Q=1.6\times {{10}^{-5}}C=16\mu C\] Electrons are removed, so chare will be positive.
