NEET Physics Screw Gauge Match the Following Question
Match Column-I with Column-II.
Column-I Column-II (a) Pitch of the screw gauge (i) 0.01 mm (b) Total reading calculation (ii) Linear scale reading + circular scale reading × least count (c) Backlash error (iii) Measurement uncertainty (d) Least count (iv) 1 mm/100 divisions
Choose the correct matching:
a-i, b-ii, c-iii, d-iv
a-iv, b-ii, c-i, d-iii
a-ii, b-iv, c-iii, d-i
a-iii, b-i, c-iv, d-ii
Correct Answer
Detailed Explanation
The pitch of a screw gauge is often expressed as a measurement that can lead to a specific least count, such as 1 mm divided by the number of divisions on the circular scale, leading to 0.01 mm. The total reading calculation involves adding the linear scale reading to the product of the circular scale reading and the least count.
