Least count of screw gauge is defined as.

Assertion : A screw gauge having a smaller value of pitch has greater accuracy. Reason : The least count of screw gauge is directly proportional to the number of divisions on circular scale.

Assertion : A screw gauge having a smaller value of pitch has greater accuracy. Reason : The least count of screw gauge is directly proportional to the number of divisions on circular scale.

How can the least count of a screw gauge be decreased ?

(I) Least count of screw gauge is 0.01 mm (II) Least count of vernier calliper is 0.1mm Which one is correct?

Circular scale divisions of a screw gauge is 50. Five full rotations advances circular scale by 5mm. Statement 1- Least count of screw gauge is 0.001 cm least count = pitch/(total number of divisions)

The least count of a screw gauge is 0.005mm and it has 100 equal divisions on its head scale. Then the distance between two consecutive threads on its screw is

How are pitch and least count of a screw gauge related to each other?

In Fig. the pitch of the screw is 1 mm. Find : (i) the least count of screw gauge and (ii) the reading represented in the diagram.

The least count of a screw gauge is 0.005 cm . The diameter of wire is 0.02 cm as measured by it. The percentage error in measurement is
