The question is based on transient analysis of an RC circuit. The concept used is that under steady state, a capacitor behaves like an open circuit and the voltage across a capacitor cannot change suddenly.The circuit is redrawn at steady state before switching. All calculations and formulae are mentioned. After switching it becomes a discharging RC circuit. The time constant is calculated as follows.
