Question
student performs an experiment for determination of 
, l ≈ lm, and he commits an error of ᐃl. For T he takes the time of n oscillations with the stop watch of least count ᐃT and he commits a human error of 0.1sec. For which of the following data, the measurement of g will be most accurate?
, l ≈ lm, and he commits an error of ᐃl. For T he takes the time of n oscillations with the stop watch of least count ᐃT and he commits a human error of 0.1sec. For which of the following data, the measurement of g will be most accurate?Options
A.ᐃl = 5mm ᐃT = 0.2 sec n = 10 Amplitude of oscillation = 5 mm
B.ᐃl = 5mm ᐃT = 0.2 sec n = 20 Amplitude of oscillation = 5 mm
C.ᐃl = 5mm ᐃT = 0.1 sec n = 20 Amplitude of oscillation = 1 mm
D.ᐃl = 1 mm ᐃT = 0.1 sec n = 50 Amplitude of oscillation = 1 mm
