Figure shows a screw gauge in which circular scale has 200 divisions. Calculate the least count and radius of the wire.
A micrometre screw gauge has a positive zero error of 7 divisions, such that its main scale is marked in 1/2 mm and the circular scale has 100 divisions. The spindle of the screw advances by 1 division complete rotation.

- L.C.
- Observed diameter
- Corrected diameter
