Question

13. A physical quantity is represented by X = [MaLbT-).
If percentage error in the measurement of M, L and T
are a%, 3% and y% respectively, then maximum
percentage error in measurement of X should be
(Given that a, B and y are very small)
(1) (aa - Bb + yc)% (2) (aa + 3b + yc)%
(3) (aa - Bb - yc)% (4) (aa + Bb - yc)%​

Answer 1

Answer:

if percentage error in the measurement of M, L and T

are a%, 3% and y% respectively, then maximum

percentage error in measurement of X should be

(Given that a, B and y are very small)

(1) (aa - Bb + yc)% (2) (aa + 3b + yc)%

(3) (aa - Bb - yc)% (4) (aa + Bb - yc)%​
