Question

Three charged capacitors, $C_1=17\mu F,C_2=34\mu F,C_3=41\mu F$ and two open switches, $S_1$ and $S_2$ are assembled into a network with initial voltages and polarities, as shown. Final status of the network is attained when the two switches, $S_1$ and $S_2$ are closed. In the figure, the final charge on capacitor $C_3$ in $mC$, is closet to:

• A. Zero
• B. $410$
• C. $1200$
• D. $3300$

Answer 1

Answer: (A)

Circuit is short when both switch $S_1$ & $S_2$ is closed
So $V_{c_3}=0$
$q=0$
