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
`((DeltaL)/(L)+2.(DeltaT)/(T)) xx 100`
`=((0.1)/(100)+(2(2))/(100)) xx 100=4.1%`
