Answer:
A) 200.9s
B) 200.4s
Explanation:
Parameters given:
acceleration due to gravity, g at the equator =
acceleration due to gravity, g at the poles =
length of pendulum, l = 1m
number of oscillations = 100
The period of an oscillation is the time taken for a pendulum to complete one oscillation, and it is given as:
where l = length of pendulum
g = acceleration due to gravity
A) At the equator, when g = , the period for one oscillation will be:
Hence, it will take 2.009s to complete one oscillation. To find the time for 100 oscillations
It will take 200.9s for the pendulum to complete 100 oscillations at the equator.
B) At the North pole, when g = , the period for one oscillation will be:
Hence, it will take 2.004s to complete one oscillation. To find the time for 100 oscillations:
It will take 200.4s for the pendulum to complete 100 oscillations at the North pole.
