Question Set 2.1: Uncertainty with Analog Scales 1. Determine the width of the pencil at right, including uncertainty. The small graduation lines indicate millimeters. What is the relative uncertainty of your reading? (Remember, we will always express the relative uncertainty as a percentage) 2. Let's compare your results from question 1 to the from the measurement of the width of the lab table on page 13. a. Which measurement has greater absolute uncertainty? b. Which measurement has greater relative uncertainty? c. Comment on why there is such a difference in relative uncertainty. 3. Determine the reading on the speedometer at right, including uncertainty. What is the relative uncertainty of your reading? Draw a number line with error bars to describe this measurement. 4. Determine the reading on the beam balance at right, including uncertainty. What are the absolute and the relative uncertainty of your reading? 100 200 100 50 8 5 1 150 200 300 250 300 350 60 70 308-309 2 400

want any specific question to be solved then please specify the question number or post
only that question.”
We cannot give the absolutely correct value of any observation. There will always be an error present inside it. The error or uncertainty which comes on measuring dimension by scale is the instrumental error. This comes because of least count of the centimeter scale. We find this uncertainty and also relative uncertainity.
