In an experiment, the period of oscillation of a simple pendulum was observed to e 2.63 s, 2.56 s, 2.42 s, 2.71 s and 2.80 s. the mean absolute error is

A

0.1 s

B

0.11 s

C

0.01 s

D

1.0 s

Text Solution

Verified by Experts

The correct Answer is:
B
Average time period
`=(2.63+2.56+2.42+2.71+2.80)/(5)`
`(13.12)/(5)=1.624=2.62s`
Average absoulte error
`=(0.01+0.06+0.20+0.09+0.18)/(5)=(0.54)/(5)`
`=0.108=0.11s`.
