The error in the measurement of the length of a simple pendulum is `0.1%` and the error in the time period is `2%`. What is the possible percentage of error in the physical quantity having the dimensional formula `LT^(-2)`?

Explanation

Percentage error is `LT^(-2)` is
`delta a = ((Delta L)/(L) + 2. (Delta T)/(T)) xx 100 = (0.1/100 + (2(2))/(100)) xx 100 = 4.1%`.
