Calculate percentage error in the determination of `g = 4pi^2 I//t^2,` when I and t are measured with `+- 2% and +- 3%` errors respectively.

Text Solution

Verified by Experts

Here, `g = 4 pi^2 I//t^2 :. (Deltag)/(g) xx 100 = +-((Delta I)/(I) xx100 +2 (Deltat)/(t ) xx100) = +-(2 +- 2xx3)% = +-8%`
