In the circuit shown in the figure the capacitor is initially uncharged
When the capacitor gets fully charging switch S2 is opened. It is observed that after 5 sec, the current in R1 is 0.74 mA. [l n(2.25) = 0.812].
(A) C = 100 μF approximately
(B) C = 50 μF approximately
(C) The charge on the capacitor at the instant mentioned in the question is aproximately equal to 2 mC
(D) Both (A) and (C) are correct
