NEET Physics Simple Harmonic Motion MCQ Question
A simple pendulum is executing simple harmonic motion with a time period T. If the length of the pendulum is increased by 21%, the percentage increase in the time period of the pendulum of increased length is
10%
21%
30%
50%
Correct Answer
Detailed Explanation
The time period T is proportional to the square root of the length. A 21% increase in length results in approximately a 10% increase in the time period.
