A student measures the period of a simple pendulum of length \(L=0.50\) m using a stopwatch. Ten successive readings (in seconds) are: 1.42, 1.44, 1.41, 1.43, 1.45, 1.40, 1.44, 1.42, 1.43, 1.41. The stopwatch has a systematic error of +0.02 s per reading, and the length measurement has an uncertainty of \(\pm0.001\) m. After correcting for the systematic error, determine the best estimate of the acceleration due to gravity \(g\) (in m·s\(^{-2}\)) and the combined standard uncertainty (expressed as a single standard uncertainty). Give \(g\) to two decimal places.

Answer Options

A. \\(g = 9.95 \\pm 0.07\\ \\text{m·s}^{-2}\\)
Correct Answer B. \(g = 10.00 \pm 0.07\ \text{m·s}^{-2}\)
C. \\(g = 10.00 \\pm 0.09\\ \\text{m·s}^{-2}\\)
D. \\(g = 10.05 \\pm 0.07\\ \\text{m·s}^{-2}\\)
Correct Answer
B
Correct Option:
\(g = 10.00 \pm 0.07\ \text{m·s}^{-2}\)
