A hollow cylinder has a charge $q\,\, C$ within it. If $ \Phi $ is the electric flux in unit of voltmeter associated with the curved surface $B$, the flux linked with the plane surface $A$ in unit of voltmeter will be

Two infinitely long parallel conducting plates having surface charge densities $+\sigma$ and $-\sigma$ respectively, are separated by a small distance. The medium between the plates is vacuum. It $\varepsilon_{0}$ is the dielectric permittivity of vacuum, then the electric field in the region between the plates is:
