NEET AIPMT SOLVED PAPER SCREENING 2011

  • 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

    A)  be reduced to half         

    B)  remain the same

    C)         be doubled          

    D)         increase four times

    Correct Answer: A

    Solution :

    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.
