A simple pendulum of length 1 m is oscillating with an angular frequency 10 rad/s. The support of the pendulum starts oscillating up and down with a small angular frequency of 1 rad/s and an amplitude of 10 –2 m. The relative change in the angular frequency of the pendulum is best given by :

1. 1 rad/s
2. 10 –3 rad/s
3. 10 –1 rad/s
4. 10 –5 rad/s

Correct answer: 10 –3 rad/s
