Vedclass · Answer

(C) $1$. Initial charge on the $2 \mu F$ capacitor is given by $Q = C_1 V_1 = 2 \mu F 	imes 60 \ V = 120 \mu C$.$2$. When the battery is disconnected and the capacitor is connected in parallel with an uncharged $1 \mu F$ capacitor,the total charge $Q$ is conserved and shared between the two capacitors.$3$. The equivalent capacitance of the parallel combination is $C_{eq} = C_1 + C_2 = 2 \mu F + 1 \mu F = 3 \mu F$.$4$. The common potential difference $V'$ across the capacitors is given by $V' = \frac{Q}{C_{eq}} = \frac{120 \mu C}{3 \mu F} = 40 \ V$.$5$. Since the capacitors are in parallel,the potential difference across the $2 \mu F$ capacitor is also $40 \ V$.
