For the circuit shown in Fig. 5 below, the capacitor is initially uncharged. At t = 0 sec,
the switch is placed in position 1 for 15 ms. Then it is placed in position 2 where it remains.
(a) Calculate the time taken for the capacitor voltage to charge to 130V.
(b) What is the capacitor voltage after 17 ms?
