Question

FORCED OSCILLLATION QUIZ.

Answer 1

The solution for Forced Harmonic motion is given by:
\[Q = Q_{1}e^{\left( -(R/2L)+\sqrt{(R/2L)^{2} - \omega_{o}^{2}} \right)t} + Q_{2}e^{\left( -(R/2L) - \sqrt{(R/2L)^{2}-\omega_{o}^{2}} \right)t} \]
If \(Q = A \cos \theta \) and \(\frac{ dQ }{ dt } \approx -\omega A \sin \theta t\) at t =0, also known that \(R/L \approx 0 \) and \(\theta \approx \pi/2\)
Find the value of Q1 and Q2!

Hbu???

Answer 2

@Algebraic!

Answer 3

i got Q1=Q2 = 1/2 A cos theta.,

Answer 4

seems correct

Answer 5

how to draw a graph Q vs t with quantitative data??

Answer 6

yess its correct and to draw graph you can either draw on graph paper with neumerical value or you can use logarithmic graph paper

Answer 7

very nice, thank u., ok i'll try..,

Answer 8
