Define the least count of an instrument.

Statement-I:The length of an object is measured with two instruments as l =4.01cm and l =4.009cm, The second instrument has a better resolution Statement-II: More value is the least count of an instrument, better is the resolution.

A vernier calliper has 20 divisions on the vernier scale. One centimetre on the main scale is divided into 20 equal parts. Find the least count of this instrument.

Explain the meaning of the term 'least count of an instrument' by taking a suitable example.

(A): The order of accuracy of a measurement depends on the least count of the instrument. (R): The smaller the least count, more number of significant figures are in the measured value.

in an experiment the angles are required to be using an instrument, 29 divisions of the main scale exactly coincide with the 30 divisions of the vernier scale. If the sallest division of the main scale is half- a degree (= 0.5^(@) , then the least count of the instrument is :

In a experiment the angle are required to be measured using an instrument. 26 divisions of the main scale exactly coincide with the 30 divisions of the vernier scale . If the smallest division of the main scale is half -a-degree (=0.5^(@)) then the least count of the instrument is .
