A screw gauge gives the following reading when used to measure the diameter of a wire. Main scale reading : 0 ~mm Circular scale reading : 52 divisions Given that 1 ~mm on main scale corresponds to 100 divisions of the circular scale. The diameter of wire from the above date is :

Options

  1. A0.052 ~cm
  2. B0.026 ~cm
  3. C0.005 ~cm
