The mean time period of second's pendulum is 2.00 s and mean absolute error in the time period is 0.05s. To express maximum estimate of error, the time period should be written as

Options

A. `(2.00+-0.01)s`
B. `(2.00+-0.025)s`
C. `(2.00+-0.05)s`
D. `(2.00+-0.10)s`

Answer

C

Explanation

Mean time period`T=2.00`sec
and Mean absolute error`=triangleT=0.05` sec
To express maximum estimate of error, the time period should be written as `(2.00+-0.05)` sec
