The amplitude of damped oscillator becomes half in one minute. The amplitude after 3 minutes will be `1//x` times the original, where x isA. 8B. 2C. 3D. 4 |
|
Answer» Correct Answer - A The variation in amplitude of damped harmonic oscilator with time is given by `A=A_(0)e^(-bt)` `A_(0)`=Initial amplitude, b=damping factor It is given that after 1 minute, `A_(1)=A_(0)//2=A_(0)e^(-bt)` `:. 2=e^(b)` `:.` after 3 minutes, `A_(3)=A_(0)//x=A_(0)e^(-3b)` `:. x=2^(3)` |
