In an LCR circuit as shown below both switches are open initially. Now switch S 1 is closed, S 2 kept open. ( q is charge on the capacitor and τ = RC is capacitive time constant). Which of the following statement is correct?

Options:

Answer:
A
Solution:

q = CV 1 - e t / τ

At t = 2 τ

q = CV 1 - e - 2
