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

  • question_answer
    A charge Q is enclosed by a Gaussian spherical surface of radius R. If the radius is doubled, then the outward electric flux will    [AIPMT (S) 2011]

    A) be reduced to half

    B) remain the same

    C) be doubled

    D) increase four time

    Correct Answer: B

    Solution :

    [b] Total flux \[=\frac{\text{Net}\,\text{enclosed}\,\text{charge}}{{{\varepsilon }_{0}}}\] Hence, we can say the electric flux depends only on net enclosed charge by surface.
