Following is the text part of the solution. Graphs, diagrams, special characters and equations will not appear here. Please see the attached file for a complete solution. Thank You.
=======================
Sum of voltage around a loop = 0 (given in your equation chart)
Therefore,
V2 = I R + Q /C
During the charging of the capacitor, initially the capacitor did not have any charge. Current in the circuit is maximum. (Imax = V2 /R since Q = 0 at t=0)
With time, charge builds up in the ...
