Question

S. A micrometre screw gauge having a positive error of 5 divisions is used to measur diameter of wire, when reading on main scale is 3rd division and 48th circular scal 3 division coincides with base line. If the micrometer has 10 divisions to a centimetr on main scale and 100 divisions on circular scale, calculate the corrected diameter.​
