Question

how can you estimate errors in the product of different measured quantities? ​

Answer 1

When two quantities are multiplied or divided, the relative error in the result is the sum of the relative errors in the multipliers. Z ± ΔZ = (A ± ΔA) (B ± ΔB) = AB ± B ΔA ± A ΔB ± ΔA ΔB. Dividing LHS by Z and RHS by AB we have, 1 ± (ΔZ/Z) = 1 ± (ΔA/A) ± (ΔB/B) ± (ΔA/A)(ΔB/B).
