If there is an error of

2\%

in measuring the length of a simple pendulum, then percentage error in its period is

View answer and explanation

Correct option: A

1\,\%

Option A (

1\,\%

) is correct because the percentage error in the time period is half the percentage error in the length, as the period is proportional to the square root of the length.
