A student performs an experiment for the determination of g= 4π^2l/T^2, he commits an error of Al. For that he takes the time of n oscillations with the stop watch of least count AT and he commits a human error of 0.1 sec. For which of the following data, the measurement of g will be most accurate [2006]
