Question

A capacitor of capacitance $C$ is charged with a battery of emf $E$. What is the flux of electric field through the Gaussian surface highlighted with dotted line?

• A. $\frac{CE}{{ϵ}_0}$
• B. $\frac{2CE}{{ϵ}_0}$
• C. $\frac{CE}{2{ϵ}_0}$
• D. $0$

Answer 1

The correct option is D $0$

Method $1:$- The electric field is parallel to the part of the gaussian surface perpendicular to the plates, and the electric field inside the conductor is zero under electrostatic condition of charges. So, the flux of the field will be zero.
