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

  • A
    $\frac{q}{2\varepsilon_0}$
  • B
    $\frac{\phi}{3}$
  • C
    $\frac{q}{\varepsilon_0} - \phi$
  • D
    $\frac{1}{2}\left(\frac{q}{\varepsilon_0} - \phi\right)$
