At first we have to calculate potential difference across the capacitors using Kirchhoff's voltage law (as the switch was in that position for a long time, it means capacitors are fully charged).

Due to shortage of time , i am not able to solve your second question. You can solve that part using the same process or upload it separately.
For any doubt please comment.

The switch has been in position "a" for a long time. At time t = 0, the switch moves from position a to position b. The switch is a "make-before-break" type: that is, the connection at position b is established before the connection at position a is broken, so there is no interruption of the current through the inductor. Questions 1. Determine the initial value of the current. 2. Determine the final value of the current and the time constant. 3. Complete Solution for...
