Which of the following energy-time graph...

Which of the following energy-time graphs represents dajmped harmonic oscillator?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C
The energy of the damped harmonic oscillator is
`E=(1)/(2)kA^(2)e^(-bt//m)` . . . (i)
Where the symbols have their usual meanings.
Eq. (i) shows that energy of the damped hramonic oscillator decreases exponentially with time. Hence, option (c) represents the correct graph.
