Question
The mass of an object is recorded as (75.50 ± 0.50) g. What is the relative (fractional) uncertainty in the mass?
Correct Answer
Option A is the correct answer.
Detailed Explanation
Relative uncertainty is calculated as the absolute uncertainty divided by the measured value. In this case, Δm/m = 0.50 g / 75.50 g ≈ 0.00662, which rounds to 0.0066.
Hint
Relative uncertainty has no units and is found by dividing the absolute uncertainty by the measurement itself.
