A tuned amplifier circuit is used to generate a carrier frequency of 2MHz for the amplitude modulation. The value of sqrt(LC) is

Answer»

`(1)/(2 PI xx 10^(6))`
`(1)/(2 xx 10^(6))`
`(1)/(3 pi xx 10^(6))`
`(1)/(4 pi xx 10^(6))`

SOLUTION :`f = (1)/(2pi sqrt(LC)) RARR sqrt(LC) = (1)/(2pi f) = (1)/(2 pi xx 2 xx 10^(6)) = (1)/(4pi xx 10^(6))`
