A screw gauge has least count of 0.01 mm and there are 50 divisions in its circular scale.
The pitch of the screw gauge is :
  1. A
    0.25 mm
  2. B
    0.5 mm
  3. C
    1.0 mm
  4. D
    0.01 mm

Correct answer: B

Least count of screw gauge

= PitchNo of divisions on circular scale\frac{Pitch}{No\ of\ divisions\ on\ circular\ scale} No of divisions on circular scalePitch​

0.01 mm = Pitch50{{Pitch} \over {50}}50Pitch​

Pitch = 0.5 mm
