A spherometer has 100 equal divisions marked along the periphery of its disc, and one full rotation of the disc advances on the main scale by 0.01cm. Find the least count of the system.

Text Solution

Verified by Experts

Given Pitch = 0.01cm
`therefore ` Least count = `("Pitch")/(" Total no. of divisions on the circular scale") = (0.01)/(100)` cm `= 10^(-4)` cm.
