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.

Step 1 of 3:

It is given that the uncertainty in the measurement of certain scale is 2%.

Also it is given that the uncertainty is proportional to the value of measurement.

We have to express the uncertainty in terms of grams corresponding to the given measurements.
