A block of mass \( 1 \mathrm{~kg} \) attached to a spring is made to
P oscillate with an initial amplitude of \( 12 \mathrm{~cm} \). After 2 minutes

W) the amplitude decreases to \( 6 \mathrm{~cm} \). Determine the value of the damping constant for this motion. (take \( \ln 2=0.693 \) )
[JEE Main-2021 (March)]
(a) \( 0.69 \times 10^{2} \mathrm{~kg} \mathrm{~s}^{-1} \)
(b) \( 3.3 \times 10^{2} \mathrm{~kg} \mathrm{~s}^{-1} \)
(c) \( 1.16 \times 10^{-2} \mathrm{~kg} \mathrm{~s}^{-1} \)
(d) \( 5.7 \times 10^{-3} \mathrm{~kg} \mathrm{~s}^{-1} \)
