Q. The mean time period of second’s pendulum is 2.00$s$ and mean absolute error in the time period is 0.05$s$. To express maximum estimate of error, the time period should be written as
A) $(2.00 \pm 0.01)\ s$
B) $(2.00 + 0.025)\ s$
C) $(2.00 \pm 0.05)\ s$
D) $(2.00 \pm 0.10)\ s$
Explanation
Mean time period $T = 2.00\ \sec$ & Mean absolute error = $\mathrm{\Delta}T = 0.05\ \sec$ To express maximum estimate of error, the time period should be written as $(2.00\ \pm 0.05)\sec$
