  • a)
    2.25 mm
  • b)
    2.20 mm
  • c)
    1.20 mm
  • d)
    1.25 mm
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
In a screw gauge, the zero of mainscale coincides with fifth division ...
Least count = 0.5/50 = 0.01mm
Zero error = 5 × L.C = 5 × 0.01 mm = 0.05 mm
Diameter of ball = [Reading on main scale] + [Reading on circular scale × L . C] – Zero error = 0.5 × 2 + 25 × 0.01 – 0.05  = 1.20 mm
