    A capacitor of capacitance C is charged to a potential V. The flux of the electric field through a closed surface enclosing the capacitor is
    (a)
    CVε0
    (b)
    2 CVε0
    (c)
    CV2ε0
    (d) zero.
    digAnsr:   d
    Ans : (d) zero

    Since the net charge enclosed by the Gaussian surface is zero, the total flux of the electric field through the closed Gaussian surface enclosing the capacitor is zero.
    `` \Phi =∯E.ds=\frac{q}{{\in }_{0}}``= 0
    Here,
    `` \Phi `` = Electric flux
    q = Total charge enclosed by the Gaussian surface.
