A pendulum with a period of 2.00000 s in one location
(g = 9.80 m/s2)
is moved to a new location where the period is now 1.99757 s. What is the change in acceleration (in m/s2) due to gravity at its new location?
Time period of a pendulum is
Assuming L to be the same in both locations,
first location:
second location:
Let be the acceleration due to gravity in second location
Therefore,
dividing these equations, we get
Change in acceleration is
