The pitch of a screw gauge is 0.5m and there are 50 divisins on its circular scale and one man scale division =0.5mm. Before starting the measurement, it is found that when jaws of the screw gauge are brought in contact, the zero of the circular scale lies 5 divisions above the reference line. When a metallic wire is placed betwen the jaws, four main scale divisions are clearly visible and 16^(th) division on the circular scale coincides with the reference line. The diameter of the wire is

1.	The pitch of a screw gauge is 0.5m and there are 50 divisins on its circular scale and one man scale division =0.5mm. Before starting the measurement, it is found that when jaws of the screw gauge are brought in contact, the zero of the circular scale lies 5 divisions above the reference line. When a metallic wire is placed betwen the jaws, four main scale divisions are clearly visible and 16^(th) division on the circular scale coincides with the reference line. The diameter of the wire is
