The acceleration due to gravity on the surface of the moon is 1.7m/s2. What is the time period of a simple pendulum on the surface of moon if it’s time period on the surface earth is 3.5 seconds?(g on the surface of earth is 9.8m/s2).

a
8.4 seconds
b
9.2 seconds
c
7.4 seconds
d
6.4 seconds

detailed solution

Correct option is A

acceleration dure to gravity,  gmoon=gm=1.7ms-2   gearth=ge=9.8ms-2 time period on earth is Tearth=Te=3.5s-1 As Te=2πlge---(1) time period on moon = Tmoon=Tm=2πlgm---(2) divide equation (2) by (1) TmTe=gegm Tm=Tegegm Tm=3.59.81.7=8.4 seconds
