A hollow cylinder has a charge q coulomb within it. If `phi` is the electric flux in units of voltmeter associated with the curved surface B, the flux linked with the plane surface A in units of voltmeter will be
Options:
(a) `q/(2epsilon_0)`
(b) `phi/3`
(c) `q/(epsilon_0)-phi`
(d) `1/2(q/(epsilon_0)-phi)`
