JEE Main & Advanced Physics Electrostatics & Capacitance JEE PYQ-Electrostatics and Capacitance

  • question_answer
    Two points P and Q are maintained at the potentials of 10V and -4V, respectively. The work done in moving 100 electrons from P to Q is                                               [AIEEE 2009]

    A) \[9.60\times {{10}^{17}}J\]

    B) \[9.60\times {{10}^{17}}J\]

    C) \[2.24\times {{10}^{16}}J\]

    D) \[2.24\times {{10}^{16}}J.\]

    Correct Answer: D

    Solution :

    [d] \[W=100\times 1.6\times {{10}^{-19}}\times 14\] \[=2.24\times {{10}^{-16}}J\]
