JEE MAIN - Physics (2020 - 9th January Evening Slot - No. 12)

Two identical capacitors A and B, charged to the same potential 5V are connected in two different circuits as shown below at time t = 0. If the charge on capacitors A and B at time t = CR is QA and QB respectively, then (Here e is the base of natural logarithm) JEE Main 2020 (Online) 9th January Evening Slot Physics - Semiconductor Question 141 English
QA = $${{CV} \over e}$$, QB = $${{VC} \over 2}$$
QA = $${{CV} \over 2}$$, QB = $${{VC} \over e}$$
QA = VC, QB = $${{VC} \over e}$$
QA = VC, QB = CV

Explanation

In case I diode is reverse biased

QA = CV

In case II, current will flow as diode is forward biased.

QA = $${{CV} \over e}$$
