Question

The period of oscillation of a simple pendulum in an experiment is recorded as 2.63 s, 2.56 s, 2.42 s, 2.71 s and 2.80 s respectively:-

G1 Physics · Accepted Answer

Mean period=(2.63+2.56+2.42+2.71+2.80)/5=2.624≈2.62 s, so A is true. Mean absolute error≈0.107 s, giving percentage error≈4.1%, closest to 4.2%, so D is true. Correct answers: A,D.
