Length of 20 cm (exact) long pipe is measured by two instruments and reported as 19.65 cm and 20.1 cm

A

19.65 cm is more accurate

B

Both measurements are equally precise

C

Both measurements are equally accurate

D

20.1 cm is less precise

Text Solution

Verified by Experts

The correct Answer is:
D

Accuracy is closeness to true /value.
Precision is based on instrument, more decimal places in measurement indicate more precision. So, 20.1 cm is less precise as compared to 19.65 cm, because 20.1 cm has lesser number of decimal places.
