In a given slide callipers 10 division of its vernier coincides with its 9 main scale divisions. If one main scale division is equal to 0.5 mm then find its least count.

Text Solution

Verified by Experts

The correct Answer is:
`0.05 mm`
Least count = 1 MSD = 1 VSD
`= 0.5 - (9)/(10)(0.5)=0.05 mm`
