Question

When an oscillator completes 100 oscillations its
amplitude reduced to 1/3 of initial value. What will
be its amplitude, when it completes 200
oscillations?​

Answer 1

Answer:

Now, when t = 100 T, a = a0/3 [T is time period] Let the amplitude be a' at t =200 T. i.e. after completing 200 oscillations. ∴ The amplitude will be reduced to 1/9 of initial value.
