Class 11PhysicsOscillationsDifferent types of oscillations (Free, Damped, Forced Oscillation and Resonance)
MediumIn damped oscillations,the damping force is directly proportional to the speed of the oscillator. If the amplitude becomes half of its initial value $A_0$ in $1 \, s$,then after $2 \, s$,the amplitude will be:
- A$\frac{1}{4} A_0$
- B$\frac{1}{2} A_0$
- C$A_0$
- D$\frac{\sqrt{3} A_0}{2}$

If the amplitude of a damped harmonic oscillator becomes half of its initial amplitude in a time of $10 \ s$, then the time taken for the mechanical energy of the oscillator to become half of its initial mechanical energy is (in $s$)
The amplitude of a damped oscillator varies with time as $A(t) = A_0 \exp(-bt / 2m)$, where $b = 70 \text{ g/s}$ and $m = 200 \text{ g}$. How long does it take for the mechanical energy to drop to one-fourth of its initial value (in $s$)? (Take $\ln 2 = 0.7$)
