What is the least count of a standard screw gauge

Circular scale of a screw gauge moves through 4 divisions of main scale in one rotation. If the number of divisions on the circular scale is 200 and each division of the main scale is 1 mm., the least count of the screw gauge is

If the number of divisions on the circular scale is 100 and number of full rotations given to screw is 8 and distance moved by the screw is 4 mm, then what will be least count of the screw gauge ?

Define least count. Describe the method to find the least count of a screw gague.

the least count of the main scale of a screw gauge is 1 mm. the minimum number of divisions on its circular scale required to measure 5 mu m diameter of a wire is :

In a screw gauge, the main scale has divisions in millimetre and circular scale has 50 divisions. The least count of screw gauge is

When circular scale of a screw gauge carrying 100 divisions is given four complete rotation, the head of the screw moves through 2mm. Calculate pitch and least count of the screw gauge.

A screw gauge has 50 divisions on its circular scale. The circular scale is 4 units ahead of the pitch scale marking , prior to use. Upon one complete ratation of the circular scale, a displacement of 0.5 mm is noticed on the pitch scale . The nautre of zero error involved , and the least count of the screw gauge, are respectively.

The circular scale of a screw gauge has 200 divisions. When it is given 4 complete rotations, it moves through 2mm . The least count of the screw gauge is
