A student measured the diameter of a wire using a screw gauge with least count 0.001 cm and listed the measurements. The correct measurement is:
As we learnt in
Significant figures -
The figures of a number that express a magnitude to a specified degree of accuracy
The least count of screwgauge is smallest length which can be measured accuretly with it. At least count 0.001 cm
Hence measured value should be recorded up to 3 decimal i.e 5.320 cm
