Answer:
option B
Explanation:
Given.
length of block measured = 11.23 cm ± 0.03 cm
vernier caliper is used to measure with uncertainty of 0.01 cm
total uncertainty = ?
The Vernier Caliper is an instrument which is used to measure the distance, diameter of the coin or many more things accurately
Accuracy of vernier caliper is equal to 0.001 of an inch.
when you convert 0.001 of an inch you will get
1 inch = 25.4 mm
0.001 inch = 0.0254 mm
or 0.002 cm
hence, total uncertainty in the measurement = 0.03 + 0.002 = 0.032 cm
the correct answer is option B
The total uncertaninity in the measurement of the length of the block is 0.032 cm
