physics,, do i have to change units micro to others?

Question

Consider a series RC circuit for which R = 7.0 M, C = 3.0 µF, and = 33 V. Find the charge on the capacitor 14 s after the switch is closed.
???????????

Answer 1

The M (meg = million) and the micro (1/1,000,000) will cancel each other out when you multiply to get the time constant.
