The mean length of an object is `5cm`. Which of the following measurement is most accurate?

A

4.9 cm

B

4.805 cm

C

5.25 cm

D

5.4 cm

Text Solution

Verified by Experts

The correct Answer is:
A
Given length, `l` = 5 cm
Now, checking the errors with each options one by one, we get
`Deltal_(1)`=5-4.9=0.1 cm
`Deltal_(2)` = 5-4.805=0.195 cm
`Deltal_(3)` = 5.25-5=0.25 cm
`Deltal_(4)` = 5.4-5=0.4 cm
Error `Deltal_(1)` is least.
Hence, 4.9 cm is most accurate.
