STANDARD Physics Propagation of Errors MCQ Question

Type: MCQ-conceptual-Medium-Class 11

If Z = A⁴B¹/³ / CD³/² and ΔA, ΔB, ΔC and ΔD are their absolute errors in A, B, C and D respectively. The relative error in Z is:

A

ΔZ/Z = ΔA/A + 1/3 ΔB/B + ΔC/C + 3 ΔD/2D

B

ΔZ/Z = ΔA/A + 1/3 ΔB/B - ΔC/C + 3 ΔD/2D

C

ΔZ/Z = ΔA/A + 1/3 ΔB/B + ΔC/C - 3 ΔD/2D

D

ΔZ/Z = ΔA/A + 1/3 ΔB/B - ΔC/C - 3 ΔD/2D

Correct Answer

Option A

Detailed Explanation

The relative error in Z is given by ΔZ/Z = ΔA/A + 1/3 ΔB/B + ΔC/C + 3 ΔD/2D. This is derived from the formula for propagation of errors in a product or quotient.
