Micro screw Gauge is used for an experiment in the physics lab. This instrument has a pitch of 0.2 mm and a circular scale with 20 divisions is used to measure the thickness of a thin sheet of iron sheet. Just before the experiment, it was observed that the two jaws of the instrument are brought in contact, the 15th division overlaps with the main scale line and that the zero of the main scale is invisible. What is the thickness of the sheet if the main scale reading is 0.9 mm and the 19th division coincides with the main scale line?
