A 6.0 V battery is being used to charge a 5.0x10^-6 F capacitor through a resistor R. The capacitor attains a potential difference of 3.6 V in 1 second after the charging begins. The value of the resistance R is?

Been stuck on this for a while and if anyone can point me into the right direction that will be great.
