A student performs an experiment for determination of `g = (4pi^(2) l)/(T^2)` and he commits an error of `Delta l `. For that he takes the time of n oscillations with the stop watch of least count `Delta T` and the commits a human error of 0.1 sec. For which of he following data, the measurement of g will be most accurate?

Options

A. `Delta l to 5 mm , Delta T to 0.2 sec , n to 10, "Ampli . Of oscill. to 5 mm`
B. `Delta l to 5mm, Delta T = 0.2 , n to 10 , "Ampli of oscill. " to 5mm`
C. `Delta l to 5mm , Delta T to 0.1 sec, n to 20 , "Ampli. Of oscill. " to 1mm`
D. `Delta l to 1mm , Delta T to 0.1 sec , n = 20 , "Ampli of oscill. " to 1mm`

Answer

D
