At \( \mathrm{t}=0 \), switch \( \mathrm{S} \) is closed. The charge on the
\( \mathrm{P} \) capacitor is varying with time as \( \mathrm{Q}=\mathrm{Q}_{0}\left(1-\mathrm{e}^{-\alpha}\right) \).

W.
Obtain the value of \( \mathrm{Q}_{0} \) and \( \alpha \) in the given circuit.
(A) \( Q_{0}=\frac{C V R_{2}}{R_{1}+R_{2}}, \alpha=\frac{R_{1}+R_{2}}{C R_{1} R_{2}} \)
(B) \( \quad Q_{0}=\frac{C V R_{1}}{R_{1}-R_{2}}, \alpha=\frac{R_{1}-R_{2}}{C R_{1} R_{2}} \)
(C) \( Q_{0}=\frac{R_{1}+R_{2}}{C V R_{2}}, \alpha=\frac{R_{1}+R_{2}}{C R_{1} R_{2}} \)
(D) \( Q_{0}=\frac{C V R_{2}}{R_{1}+R_{2}}, \alpha=\frac{C R_{1} R_{2}}{R_{1}+R_{2}} \)
