A series combination of resistor ( R ), ...

A series combination of resistor ( R ), capacitor ( C ) is connected to an .C. source of angular frequency `omega`. Keeping the voltage same, if the frequency is charged to `(omega)/(3)`, the current becomes half of the original current. Then the ratio of the capacitive reactance and resistance at the former frequency is

A

`sqrt0.6`

B

`sqrt3`
