Answer:

To determine the main scale division of the vernier calipers, we can use the information provided.

The least count of the instrument is given as 0.1 mm. The least count represents the smallest measurement that can be made using the instrument. It is calculated by dividing the main scale reading by the number of divisions on the vernier scale that coincide with a given number of divisions on the main scale.

In this case, the vernier scale has 40 divisions that coincide with 38 divisions on the main scale. So, the least count can be calculated as follows:

Least Count = Main Scale Reading / Number of Vernier Scale Divisions

0.1 mm = Main Scale Reading / 40

To find the main scale reading, we can rearrange the equation:

Main Scale Reading = Least Count x Number of Vernier Scale Divisions

Main Scale Reading = 0.1 mm x 40

Main Scale Reading = 4 mm

Therefore, the main scale divisions on the vernier calipers are 4 mmm each
