Question

Which thing to keep in mind while measuring the length of any object?

Answer 1

"By measuring the length of an object using a ruler, we should keep in mind

the following points:

• The ruler should be placed exactly along the object

• If the end or sides of the ruler are worn out or broken that can give wrong reading. So we should take a proper ruler

• The eyes of the observer should be located exactly above the point where the measurement is intended to be taken. Eyes at different positions can give wrong readings.
