The period T and the length l of a simple pendulum are measured to be T =
Question:
The period T and the length l of a simple pendulum are measured to be T = 1.5 ± 0.1 s and l = 0.560 ± 0.001 m.
The formula T = 2π√I/g is used to find the acceleration of free fall g.
What is the best estimate of the uncertainty in the value of g?
a. 0.2%
b. 3%
c. 7%
d. 13%
