<h2>Ratio of free fall acceleration of Tokyo to Cambridge = 0.998</h2>
Explanation:
We know the equation

where l is length of pendulum, g is acceleration due to gravity and T is period.
Rearranging

Length of pendulum in Tokyo = 0.9923 m
Length of pendulum in Cambridge = 0.9941 m
Period of pendulum in Tokyo = Period of pendulum in Cambridge = 2s
We have

Ratio of free fall acceleration of Tokyo to Cambridge = 0.998
