JEE MainPhysicsUnits and MeasurementsMCQ+4 / −1
There are 100 divisions on the circular scale of a screw gauge of pitch 1 mm1 \mathrm{~mm}1 mm. With no measuring quantity in between the jaws, the zero of the circular scale lies 5 divisions below the reference line. The diameter of a wire is then measured using this screw gauge. It is found that 4 linear scale divisions are clearly visible while 60 divisions on circular scale coincide with the reference line. The diameter of the wire is :
  1. A
    4.65 mm
  2. B
    4.60 mm
  3. C
    4.55 mm
  4. D
    3.35 mm
