Explanation:
The frequency of a simple pendulum is given by:
where
g is the acceleration of gravity
L is the length of the pendulum
Calling the length of the first pendulum and
the acceleration of gravity at the location of the first pendulum, the frequency of the first pendulum is
The length of the second pendulum is 0.4 times the length of the first pendulum, so
while the acceleration of gravity experienced by the second pendulum is 0.9 times the acceleration of gravity experienced by the first pendulum, so
So the frequency of the second pendulum is
Therefore the ratio between the two frequencies is
