The period of oscillation of a simple pendulum isT=2πLg.Measured value ofLis1.0 mfrom meter scale having a minimum division of1 mmand time of one complete oscillation is1.95 smeasured from stopwatch of0.01 sresolution. The percentage error in the determination of'g'will be:

Options:

Answer:
D
Solution:

T=2πg

g=4π2T2

Δgg=Δ+2ΔTT

Δgg=1×10-31+2×0.011.95

Δgg=0.0113 or 1.13%
