A screw gauge has least count of 0.01mm0.01mm and there are 5050 divisions in its circular scale. The pitch of the screw gauge is:

Options

  1. A0.25mm0 .25 mm
  2. B0.5mm0 .5 mm
  3. C1.0mm1 .0 mm
  4. D0.01mm0 .01 mm

Correct answer

B. 0.5mm0 .5 mm

Step-by-step solution

The least count on screw gauge is given by,L.C.=PitchNumber of division on circular scale\text{L.C.} = \dfrac{\text{Pitch}}{\text{Number of division on circular scale}}

⇒0.01mm=Pitch50⇒ 0 . 01mm = \dfrac{Pitch}{50}

⇒Pitch=0.5mm⇒ Pitch = 0 . 5mm
