NEET Physics Screw Gauge Match the Following Question
Match Column-I with Column-II.
Column-I Column-II (a) Backlash Error (i) Consistency in reading measurements (b) Pitch of Screw (ii) Distance moved by the screw per rotation (c) Circular Scale (iii) Represents divisions on the screw gauge (d) Linear Scale (iv) Affected by screw-nut fit
Choose the correct matching:
a-iv, b-ii, c-iii, d-i
a-ii, b-iv, c-i, d-iii
a-iii, b-i, c-ii, d-iv
a-i, b-iii, c-iv, d-ii
Correct Answer
Detailed Explanation
Backlash error occurs when there is a looseness in the screw-nut fit, affecting measurement precision as stated in the context. The pitch of the screw is defined as the distance moved by the screw for one complete rotation, which is critical for accurate measurement. The circular scale indicates the divisions, while the linear scale provides consistency in reading measurements.
