Figure shows a horizontal parallel plate capacitor is lowered on a liquid surface in such a way that its lower plate is just submerged in the liquid of dielectric constant `k`. Find the height to which the liquid level will be raised between the plates if the capacitor plates are given a surface charge density `+sigma` and` -sigma` on its plates.
