A screw gauge has 100 divisions on the circular scale and linear distance travelled by the head scale is 5 mm in 10 complete rota of circular scale When nothing is placed between its studs the zero of circular scale is 26 divisions above the reference line it me zero error is 26 divisions on the circular scale Now if the diameter of a wire is measured by keeping the wire between its studs main scale reading is 6 divisions and 48th division of circular scale coincides with the reference line If the negative zero error of se gauge is x mm and the measured diameter of the wire is y mm of x is
