Teaching HTET PGT Level 3 - 2024 Mock Test Physics Units, Dimensions and Measurements Accuracy, precision of instruments and errors in measurement
The period of oscillation of a simple pendulum is \(T = 2π\sqrt {(L/g)}\). Measured value of ‘L’ is 1.0 m from meter-scale having a minimum division of 1 mm and time of one complete oscillation is 1.95 s measured from stopwatch of 0.01 s resolution. The percentage error in the determination of ‘g’ will be:
1
1.33 %
2
1.30 %
3
1.13 %
4
1.03 %
