A parallel plate capacitor having plate area ' $A$ ' and separation ' $d$ ' is charged to a potential difference ' $V$ '. The charging battery is disconnected and the plates are pulled apart to four times the initial separation. The work required to increase the distance between the plates is ( $\varepsilon_0=$ permittivity of free space)

$\frac{\varepsilon_0 A V^2}{3 d}$

$\frac{\varepsilon_0 A V^2}{4 d}$

$\frac{2 \varepsilon_0 A V^2}{d}$

$\frac{3 \varepsilon_0 A V^2}{2 d}$
