  • Statement I : Two point charges +Q and -Q are fixed at point A(+a,0,0) and point B(-a,0,0) respectively. Then the magnitude of electric flux due to electric field of either point charges through infinite y-z plane (that is x = 0 plane) is less than magnitude of net electric flux due to electric field of both charges through that plane (x = 0). Statement II : The magnitude of net electric flux through a surface due to a system of point charges is equal to sum of magnitude of electric flux through that surface due to each of the point charge of the system.

    A
    Statement I is True, Statement II is True, Statement II is a correct explanation for Statement I
    B
    Statement I is True, Statement II is True, Statement II is not a correct explanation for Statement I
    C
    Statement I is True, Statement II is False
    D
    Statement I is False, Statement II is True
