Question

A student performs an experiment for determination of $g = [\frac{4 π^{2} L}{T^{2}}], L = 1 m$ , and he commits an error of $△ L$ . For The takes the time of n oscillations with the stopwatch of least count $△ T$ . For which of the following data, the measurement of g will be most accurate?

△ L = 0.5, △ T = 0.1, n = 20

Solution

The correct option is C $△ L = 0.5, △ T = 0.05, n = 50$
Option D is correct
n $\to$ larger because the max the observation, less the observation
$△ T \to$ smaller
$△ L \to$ smaller
