    In order to estimate the electric field due to a thin finite plane metal plate, the Gaussian surface considered is:

    A) spherical                

    B) cylindrical 

    C) straight line            

    D) None of these

    Correct Answer: B

    Solution :

    (b) cylindrical                   In order to estimate the electric field due to a thin finite plane metal plate, we take a cylindrical cross-sectional area A and length 2r as the Gaussian surface.
