- #1A 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: dAns : (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.
