The mean time period of second's pendulum is $2.00s$ and mean absolute error in the time period is $0.05s$. To express maximum estimate of error, the time period should be written as
The mean time period of second's pendulum is $2.00s$ and mean absolute error in the time period is $0.05s$. To express maximum estimate of error, the time period should be written as
$(2.00 \pm 0.01) s$
$(2.00 \pm 0.025) s$
$(2.00 \pm 0.05) s$
$(2.00 \pm 0.10) s$
The mean time period of second's pendulum is $2.00s$ and mean absolute error in the time period is $0.05s$. To express maximum estimate of error, the time period should be written as
Mean time period $T = 2.00 \,sec$
& Mean absolute error $ = \Delta T = 0.05\, sec$.
To express maximum estimate of error, the time period should be written as $(2.00 \pm 0.05)\,sec$
