If a pendulum is 10m long, (a) what is the natural frequency and the period of vibration on the earth, where the free-fall acceleration is 9.81 m/s^2 and (b) what is the natural frequency and the period of vibration on the moon, where the free-fall acceleration is 1.67 m/s^2?

(a) Natural frequency = 0.99 rad/sec (b) 0.4086 rad/sec

Explanation:

We have given length of pendulum = 10 m

(a) Acceleration due to gravity

Time period of pendulum is given by , L is length of pendulum and g is acceleration due to gravity

So

Natural frequency is given by

(b) In this case acceleration due to gravity

So time period

Natural frequency

answer:

yes
