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