Five indentical capacitor plates, each of area $A,$ are arranged such that adjacent plates are at distance $d$ apart. The plates are connected to a source of $emf$ $V$ as shown in fig. Then the charges $1$ and $4$ are, respectively :-

A

${ \in _0}AV/d,\,2{ \in _0}AV/d$

B

$2{ \in _0}AV/d,\,-2{ \in _0}AV/d$

C

${ \in _0}AV/d,\,-2{ \in _0}AV/d$

D

${ \in _0}AV/d,\,-{ \in _0}AV/d$

Solution

$\in_{0} \mathrm{AV} / \mathrm{d},-2 \in_{0} \mathrm{AV} / \mathrm{d}$ (negative charge occurs on both sides of the plate $4$ ).
