 Mentor P: 11,618 Good morning. (*YAWN*) I took another look at the problem. A small correction is required to the time response formula. This time the exponential is starting at zero and heading towards a final value that's equal to the Thevenin voltage of the resistor network. So the form is: $$V_o(t) = V_{th} \left(1 - e^{-t/\tau} \right)$$ Regarding your "different question with the same circuit", apply the above suggested formula and recheck your result -- also check to see if the time t1 to be plugged in is the same for both problems.
