Class 11PhysicsOscillationsDifferent types of oscillations (Free, Damped, Forced Oscillation and Resonance)
Difficult$A$ block of mass $1 \, kg$ attached to a spring is made to oscillate with an initial amplitude of $12 \, cm$. After $2 \, minutes$ the amplitude decreases to $6 \, cm$. Determine the value of the damping constant $b$ for this motion. (Take $\ln 2 = 0.693$)
- A$0.69 \times 10^{-2} \, kg \, s^{-1}$
- B$3.3 \times 10^{-2} \, kg \, s^{-1}$
- C$5.7 \times 10^{-3} \, kg \, s^{-1}$
- D$1.16 \times 10^{-2} \, kg \, s^{-1}$
