The acceleration due to gravity on the surface of the moon is 1.7 ms–2. What is the time period of a simple pendulum on the surface of the moon if its time period on the surface of Earth is 3.5 s? (g on the surface of earth is 9.8 ms–2)
Acceleration due to gravity on the surface of moon, g' = 1.7 m s–2
Acceleration due to gravity on the surface of earth, g = 9.8 m s–2
Time period of a simple pendulum on earth, T = 3.5 s
Hence, the time period of the simple pendulum on the surface of the moon is 8.4 sec.
