Physics Units, Dimensions and Measurements Accuracy, precision of instruments and errors in measurement
The period of oscillation of a simple pendulum is T = 2π\(\sqrt {\frac{{\rm{L}}}{{\rm{g}}}} \). 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
1.12%
2
1.03%
3
1.13%
4
1.30%
