.Acceleration due to gravity on the surface of the moon, g'=1.7  

Acceleration due to gravity on the surface of the earth, g=9.8 
The time period of a simple pendulum on earth, T=3.5 s

and T is given as  
where
is   the length of the pendulum

And keeping l= length of the pendulum=constant

similarly, on the surface of the moon, we have time period as 

So 

So the time period of the simple pendulum on the surface of the moon is 8.4 s.
