    An ac 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 source is changed to omega /3 (but maintaining the same voltage), the current in then circuit is found to be halved. Calculate the ratio of reactance to resistance at the original frequency omega
