AIPMT PRELIMS 2002 Physics Damped Oscillations MCQ Question
Type: MCQ-numerical-Medium-Class 11
When an oscillator completes 100 oscillation its amplitude reduced to 1/3 of initial value. What will be its amplitude, when it completes 200 oscillation :-
A
1/8
B
2/3
C
1/6
D
1/9
Correct Answer
Option D
Detailed Explanation
The amplitude reduces exponentially with the number of oscillations. If the amplitude is reduced to 1/3 after 100 oscillations, it will be reduced to (1/3)² = 1/9 after 200 oscillations.
