An a.c. source of angular frequency `omega` is fed across a resistor R and a capacitor C in series. The current registered is I. If now the frequency of the source is changed to `omega//3` (but maintaining the same voltage), the current in the circuit is found to be halved. calculate the ratio of reactance to resistance at the original frequency `omega`.

A
