Question

Two capacitors C_­1 and C₂ = 2C₁ are connected in a circuit with a switch between them as shown in the figure. Initially the switch is open and C₁ holds charge Q. The switch is closed. At steady state, the charge on each capacitor will be-

• A. Q, 2Q
• B. $\frac{Q}{3}$, $\frac{2Q}{3}$
• C. $\frac{3Q}{2}$, 3Q
• D. $\frac{2Q}{3}$, $\frac{4Q}{3}$

Answer 1

Answer: (B)

$\frac{Q}{3}$, $\frac{2Q}{3}$

Answer 2

After joining potential remains same

\ Q₁ =

Q Q₁ + Q₂ = Q \ Q₁ =, Q₂ =
