Question

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

• A.
• B.
• C.
• D.

Answer 1

Answer: (C)

Answer 2

The energy of the damped harmonic oscillator is $E=\frac{1}{2} KA^{2}e^{-bt m}$ $\ldots\left(i\right)$ where the symbols have their usual meanings E (i) shows that energy of the damped harmonic oscillator decreases exponentially with time. Hence, option (c) represents the correct graph.
