Which of the following length measurment...

Which of the following length measurment is most accurate and why ? (i) 4.00 cm (ii) 0.004 mm (iii) 40.00 cm.

Text Solution

Verified by Experts

`(i) (Deltax)/(x) = (0.01)/(4.00) = 0.0025`
(ii) `(Deltax)/(x) = (0.001)/(0.004) = 0.25`
(iii) `(Deltax)/(x) =(0.01)/(40.00) = 0.00025`
The last observation has the last fractional error
and hence it is most accurate.
