Assersion : Out of three meansurements `l = 0.7 m, l = 0.70m` and `l = 0.700m` the last one is most accurate.
Reason: In every meansurements only the last significant digit is not accurately known.

A

If both assertion and reason are true and reason is the correct explation of assertion.

B

If both assertion but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
b
The last number is most accuratebecause it has greater significant figure`(3)`.
