1. $0.02mm$

2. $0.05mm$

3. $0.1mm$

4. $0.2mm$

Q.

In a vernier calliper 19 main scale divisions concide with 20 vernier scale divisions .if the main scale has 20 divisions in a centimetre, calculate L.C. of vernier calliper (ans 0.0025 cm)

Q. Least count of vernier, L.C. = Value of 1 ___ scale division - value of 1 ___ scale division.

1. vernier, main
2. main, vernier
3. vernier, circular
4. main, circular

Q.

What is the least count of vernier caliper?

1. $0$

2. $0.01mm$

3. $0.001$

4. $0.1mm$

Q. The least count of a vernier callipers is equal to:

1. The difference in the values of one main scale division and one vernier scale division.
2. The length of total number of divisions on its vernier scale.
3. The length of one division on its vernier scale.
4. The value of one division on its main scale.

Q. Vernier calipers has its main scale 10 cm equally divided into 250 parts. Its vernier scale is of 50 division and coincide with 15 mm of the main scale. The least count of the instrument is :
