Question

If x = (a – b), the maximum percentage error in the measurement of x will be

(A) \(\Big[\frac{Δa}{a-b}-\frac{Δb}{a-b}\Big]\)x 100

(B) \(\Big[\frac{Δa}{a-b}+\frac{Δb}{a-b}\Big]\)x 100

(C) \(\Big[\frac{Δa}{a}+\frac{Δb}{b}\Big]\)x 100

(D) \(\Big[\frac{Δa}{a}-\frac{Δb}{b}\Big]\)x 100

Answer 1

Answer is (B) \(\Big[\frac{Δa}{a-b}+\frac{Δb}{a-b}\Big]\)x 100
