Using approximations, the average voltage across the 10 meg load is 8500 volts, so the discharge current is 850 uamp. Using the approximate relation: dE/dT = I/C then C = .04*850/3000 ufarad = .01 uf. evidently, it will take 850/50 = 17 times longer to charge the cap than to discharge it. I don't think there is a solution to the problem.
