A simple pendulum of length 1.00m is used first in a sea-level laboratory and then at the summit of a nearby hill. At sea level the time period is measured as 1.99s, whereas at the hilltop it increases to 2.01s.
(i) Calculate the value of the acceleration due to gravity at sea level.
(ii) Calculate the value of the acceleration due to gravity at the hilltop.
(iii) Find the percentage decrease in the value of g between the two locations.
