The capacitance in an oscilatory `LC` circuit is increased by `1%`. The charge in inductance required to restore its frequency of oscillation is to

A

decrease it by `0.5%`

B

increase it by `1%`

C

decrease it by `1%`

D

decrease it by `2%`

Text Solution

Verified by Experts

The correct Answer is:
C
`omega_(r) =` constant
`rArr LC =` constant
`rArr L dc + CdL = 0 rArr (dI)/(L) = - (dC)/(C ) = - 1%`
