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