Question

the time period of a pendulum on the surface of the moon is 5s .if it is a seconds pendullam on earth and the accelaration due to gravity on the earth is 9.8m s-2,find the accelartion due to gravity on the surface of the moon?

Solution

We know time period of the Simple formula is given by-T =2πLgwhere T is time period L is the length of the pendulum g is acceleration due to gravityGiven ,time period of a pendulum on the surface of the moon is 5sSo let = T' = 5 sec L will be the lenght of the pendulum.Let acceleration due to gravity on the moon is g'.So,T'= 2πLg'5 =2πLg'.......(1)On the surface of the earth , T = 2 sec(because for seconds pendulum time period is 2 sec) , g = 9.8 m/sec2 and length will remain same everywhere.So ,2= 2πL9.8.....(2)Now on dividing (1) by (2) we get5 2= 9.8g'Now on squaring both sides,we getg' = 9.8 ×425 = 1.568 1.6 m/sec2
