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

  • question_answer
    A conductor has \[14.4\times {{10}^{-19}}coulombs\] positive charge. The conductor has            (Charge on electron \[=1.6\times {{10}^{-19}}coulombs\])           

    A)                    9 electrons in excess            

    B)                    27 electrons in short           

    C)                    27 electrons in excess      

    D)                                              9 electrons in short

    Correct Answer: D

    Solution :

                 Positive charge shows the deficiency of electrons. Number of electrons \[=\frac{14.4\times {{10}^{-19}}}{1.6\times {{10}^{-19}}}=9\]
