For some measuring processes, the uncertainty is approximately proportional to the value of the measurement. For example, a certain scale is said to have an uncertainty of ±2%. An object is weighed on this scale.
a) Given that the reading is 100 g, express the uncertainty in this measurement in grams.
b) Given that the reading is 50 g, express the uncertainty in this measurement in grams.

The uncertainty of measurement in grams is defined as
(±2%) Value of Measurement
a) Given that the reading is 100 g, express the uncertainty in this measurement in grams:
Here the measurement is 100g,
Therefore uncertainty=±0.02100
Therefore uncertainty=±2g
b) Given that the reading is 50 g, express the uncertainty in this measurement in grams:
Here the measurement is 50g,
Therefore uncertainty=±0.0250
Therefore uncertainty=±1g
