In a screw gauge, the main scale has divisions in millimetre and circular scale has `50` divisions. The least count of screw gauge is

While measuring diameter of a wire using a screw gauge the main scale reading is 7mm and zero of circular scale is 35 divisions above the reference line. If the screw gauge has a zero error of -0.003cm , the correct diameter of the wire is (given least count =0.001cm )

A screw gauge has main scale divisions of 1 mm each and its circular scale has 50 division. While measuring the diameter of a ball, cap end is after 19^("th") marking of main scale and 21^("st") division of circular scale coincides with the reference line. What is the measured diameter diameter of the ball?
