In an experiment to determine the acceleration due to gravity g, the formula used for the time period of a periodic motion is T=2π(7R−r5g−−−−−−−−√. The values of Randr are measured to be (60±1)mmand(10±1)mm, repectively. In five successive measurment, the time period is found to be 0.52s,0.56s,0.57s,0.54sand0.59s. the least count of the watch used for the measurement of time period is 0.01s. Which of the following statement (s) is (are) true?
