Solution

The correct option is A $3 μ C$
When switch $1$ closed other $2$ capacitors are initially charged, But all have equal capacity of $6 μ F$ So Voltage drop across must be equal to $2 V$ .
$q = \frac{C}{V} = \frac{6}{2} μ F = 3 μ C$

the left most capacitor is uncharged. the other two capacitor carry charges q1=8μC and q2=10μC. Now switch S is closed. Find the final charge on the leftmost capacitor.

The correct option is A 3μCWhen switch 1 closed other 2 capacitors are initially charged, But all have equal capacity of 6μF So Voltage drop across must be equal to 2V.q=CV=62μF=3μC
