Question

A student performs an experiment for determination of g ( = T 2 4 π 2 l ​ ) , l ≈ 1 m , and he commits an error of Δ l . For T he takes the time of n oscillations with the stop watch of least count Δ T and he commits a human error of 0.1 s . For which of the following data, the measurement of g will be most accurate?

TestHub · Accepted Answer

g Δ g ​ = l Δ l ​ + 2 n Δ T ​ In option (d) error in Δ g is minimum and number of observations made are maximum. Hence, in this case error in g will be minimum.
