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:

Options

  1. A0 .25   mm
  2. B0 .5   mm
  3. C1 .0   mm
  4. D0 .01   mm

Correct answer

B. 0 .5   mm

Step-by-step solution

The least count on screw gauge is given by, L.C. = Pitch  Number of division on circular scale   ⇒ 0 . 01   mm = Pitch 50 ⇒ Pitch = 0 . 5   mm
