The amplitude of a damped oscillator is known to decrease to 0.9 times its original amplitude in \(5 \mathrm{~s}\). Approximately, by how many times its original amplitude will decrease after another \(20 \mathrm{~s}\) ?
- A 0.73
- B 0.9
- C 0.59
- D 0.26
Answer & Solution
Correct Answer
(C) 0.59
Step-by-step Solution
Detailed explanation
Initial amplitude, \(A_i=A_0\) Final amplitude \(A_f=0.9 A_0\) Case 1 Time \(t_1=5 \mathrm{~s}\) Case 2 Time \(t_2=20 \mathrm{~s}\) Let, amplitude after \(20 \mathrm{~s}\) be \(A^{\prime}\). As we know that,…
