Question

Pitch of the screw gauge is 0.5mm. Its head scale contains 50 divisions. The least count of it is

  1. 0.01mm    
  2. 0.1mm    
  3. 0.25mm    
  4. 0.02mm    

The correct answer is: 0.01mm


    L C equals fraction numerator 0.5 over denominator 50 end fraction semicolon equals fraction numerator 5 over denominator 500 end fraction equals 0.01 m m
