Measurement in length #shorts #ytshorts

Give one example where precise measurement of length is important.

In measures of lengths

Given relative error in the measurement of length is .02, what is the percentage error ?

What is the reliability of measurement of length using a metre scale ?

In the experiment to determine Young's modulus of the material of a wire under tension used in the arrangement as shown. The percentage error in the measurement of length is a in the measurement of the radius of the wire is b and in the measurement of the change in length of the wire is c . Percentage error in the measurement of Young's modulus for a given load is

The uncertain digit in the measurement of a length reported as 41.68 cm is

You are provided three scales A, B and C as shown in Fig. 10.6 to measure a length of 10 cm. For the correct measurement of the length you will use the scale

The pressure on a square plate is measured by measureing the force on the plate and the percentage error of measurement of force and length are respectively 4% and 2%, the maximum error in the measurement of pressure is-
