Hey,
I am stuck on a question on capacitors, I have been doing physics all day so my brain might just be fizzled out a bit, but it is bugging me so if anyone could help it would great.Thanks,

A 50 μF capacitor is charged by connecting it to a 6V battery then discharged through a 100kΩ resistor.

Calculate the charge stored in the capacitor immediately after it has been charged and the time constant of the circuit.

If the capacitor's connected directly to the battery, use C = Q/V for the first bit. The time constant, τ = RC for an RC circuit.
