Solution

The correct option is B
False

The distance moved by the tip of the screw for a rotation of one division on the head scale is called the least count of the screw gauge.

Least Count = $\frac{(P i t c h)}{(N o . o f d i v i s i o n s o n t h e h e a d s c a l e)}$

If you know the pitch and the number of divisions on the head scale, then you can determine the least count of the screw gauge. So the given statement is false.

Q. If the pitch of a screw gauge is 0.5 mm and its least count is 0.01 mm. Find the number of divisions on the head scale.

Consider a Vernier calipers in which each $1 c m$ on the main scale is divided into $8$ equal divisions and a screw gauge with $100$ divisions on its circular scale. In the Vernier callipers, $5$ divisions of the Vernier scale coincide with $4$ divisions on the main scale and in the screw gauge, one complete rotation of the circular scale moves it by two divisions on the linear scale. Then
