The time in seconds taken for 20 oscillations noted down in an simple pendulum experiment are `38.6, 40.0, 41.5, 42.8 and 39.4`, the time period of the given simple pendulum is ____ s

A

`2.5`

B

`2.2`

C

`2.0`

D

`10.1`

Text Solution

Verified by Experts

The correct Answer is:
C
`T=( 38.6 + 40+ 41.5+ 42.8 +39.4 )/((5)/(20 ))`
` = 2.023 s ~~ 2s`
