Consider a L-C oscillation circuit. Circuit elements has zero resistance initially at t = 0 the energy is stored in the form of electric field and plate -1 is having positive charge :
at time `t = t_(1)` plate -2 attains half of the maximum +ve change for the first time. Value of `t_(1)` is :

A

`(2pi)(3)sqrt(LC)`

B

`(pi)/(3)sqrt(LC)`

C

`(4pi)/(3)sqrt(LC)`

D

`pisqrt(LC)`

Text Solution

Verified by Experts

`q_(1)=q_(0) sin(omegat+pi//2)`
at `t=t_(1)" " a_(1)=-(q_(0))/(2)`
`t_(1)=(pi-(pi)/(3))/(omega)=(2pi)/(3omega)=(2pi)/(3)sqrt(LC)`
