Here the three plates will make ( $3-1$ ) $= 2$ capacitors of same capacitance $C$ and these two capacitors are connected in parallel.

here, $C=\frac{A \epsilon_{0}}{d}=\frac{0.1 	imes 8.854 	imes 10^{-12}}{0.885 	imes 10^{-3}}=1 n F$

The equivalent capacitance of the system is $C_{e q}=C+C=2 n F$

Energy stored in this system is $U=\frac{1}{2} C_{e q} V^{2}=\frac{1}{2} 	imes 2 	imes 10^{-9} 	imes 10^{2}=10^{-7} J=10^{-1} \mu J$

Three plates $A, B$ and $C$ each of area $0.1 \ m^2$ are separated by $0.885\ mm$ from each other as shown in the figure. $A$ $10$ $V$ battery is used to charge the system. The energy stored in the system is
