A capacitor with an initial potential difference of 125 V is discharged through aresistor when a switch between them is closedat t = 0.At t = 5.0 s,the potential difference across the capacitor is 1.40 V.

a) What is the time constant of the circuit?
b) What is the potential difference across the capacitor at t = 15.0 s?
