A student performs an experiment for determination of g = \(\frac{4 \pi^{2} l}{T^{2}}\) an error of ∆l. For that, he takes the time of n oscillations with the stopwatch of least count ∆T and he commits a human error of 0.1s. For which of the following data, the measurement of g will be most accurate? ∆l, ∆T, n
A. 5m, 0.2s, 10
B. 5mm, 0.2s, 20
C. 5mm, 0.1s, 20
D. 1mm, 0.1s, 50
