Question

A student uses a simple pendulum of exactly 1m length to determine g, the acceleration due to gravity. Heuses a stop watch with the least count of 1 sec for this and records 40 seconds for 20 oscillations. For thisobservation, which of the following statement(s) is (are) true?

Options

A.Error ᐃT in measuring T, the time period, is 0.05 seconds
B.Error ᐃT in measuring T, the time period, is 1 second
C.Percentage error in the determination of g is 5%
D.Percentage error in the determination of g is 2.5%

Solution


ᐃ T = 0.05 sec
g =

⇒ % error = × 100 = 5%
