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 amplitude of 10−2 m. The relative change in the angular frequency of the pendulum is best given by
a. |
10−3 rad/s |
b. |
10−1 rad/s |
c. |
1 rad/s |
d. |
10−5 rad/s |
