Electric Flux & Gauss's Law

A hollow cylinder has a charge q coulomb within it. If $\phi$ is the electric flux in units of volt-metre associated with the curved surface B, the flux linked with the plane surface A in units of V-m will be

Show answer and solution

Answer: (d)

Total flux $= \dfrac{q}{\varepsilon_0} = \phi_A + \phi_B + \phi_C$ , with $\phi_B = \phi$ .
By symmetry the two flat ends get equal flux: $\phi_A = \phi_C$ .
$2\phi_A = \dfrac{q}{\varepsilon_0} - \phi \Rightarrow \phi_A = \dfrac{1}{2}\left(\dfrac{q}{\varepsilon_0} - \phi\right)$
So the answer is (d).
