That seemed like the logical place to start, but it seems I messed up somewhere after that. Here's my attempt to solve it:
At position ‘a’:
Q = C*EMF = (20*10^-6 F)(50 V) = 0.001 C
At position ‘b’:
Q_0 = 0.001 C
Q = Q_0*e^(-t/(R*C)) = 0.001*e^((-0.00125)/(50 * 20*10^-6)) = 0.000287
dQ...
I have the solution to this problem, but I can't figure out how to solve it for the life of me. I'd appreciate any assistance:

The switch in the figure above has been in position 'a' for a very long time. It is suddenly flipped to...
