An electric lamp designed for operation on 110 V AC is connected to a 220 V AC supply, through a choke coil of inductance 2H, for proper operation. The angular frequency of the AC is \(100\sqrt {10}\) rad/s. If a capacitor is to be used in place of the choke coil, its capacitance must be
1
1 μF
2
2 μF
3
5 μF
4
10 μF
