Initially the `900 mu F` capacitor is charged to `100 V` and the `100 mu F`capacitor is uncharged in Fig. Then switch `S_(2)` is closed for time `t_(1)`, after which it is opened and at the same instant switch `S_(1)` is closed for time `t_(2)` and then opened. It is now found that `100 mu F` capacitor is charged to `300 mu F` capacitor is charged to `300 V`. Find the minimum possible value of the time interval `t_(1)` and `t_(2)`.
