NEET 2025 Physics Percentage Error Calculation MCQ Question
Type: MCQ-numerical-Easy-Class 11
A physical quantity P is related to four observations a, b, c and d as follows: P = a³b²/c√d The percentage errors of measurement in a, b, c and d are 1%, 3%, 2%, and 4% respectively. The percentage error in the quantity P is
A
10%
B
2%
C
13%
D
15%
Correct Answer
Option C
Detailed Explanation
The percentage error in P is calculated using the formula: ΔP/P = 3(Δa/a) + 2(Δb/b) + (Δc/c) + 0.5(Δd/d). Substituting the given errors gives 13%.
