A simple pendulum is how many oscillations does it make per second? (b) Whet will be the frequency if the system is taken on the moon where acceleration due to gravitation of the moon is 1.67 m s-2?

(a) 0.70/π

(b) 1/(2 π√3) Hz


(a) given l = 5m


g = 9.8 m/s2


We know, Time period T = 2∏


= 2(3.14) = 4.4857


Frequency f = =


= (1.4)


= HZ


(b) Frequency on moon fmoon = =


= HZ
