JEE Advanced 2016 Physics question
In an experiment to determine the acceleration due to gravity , the formula used for the time period of a periodic motion is . The values of and are measured to be mm and mm, respectively. In five successive measurements, the time period is found to be 0.52 s, 0.56 s, 0.57 s, 0.54 s and 0.59 s. The least count of the watch used for the measurement of time period is 0.01 s. Which of the following statement(s) is(are) true?
Answer: (A),(B),(D)
Solution
(A) : true. Mean period s. Absolute deviations: 0.04, 0.00, 0.01, 0.02, 0.03; mean absolute error s (larger than the least
