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?

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

Main scale of a screw gauge is 3mm and 42 division of circular scale of 100 divisions coincides with reference line then find the diameter of the cylinder

The pitch of a screw gauge is 1 mm and there are 100 divisions on the circular scale. In measuring the diameter of a sphere there are six divisions on the linear scale and forty divisions on circular scale coincide with the reference line. Find the diameter of the sphere.

The pitch of a screw gauge is a mm and there are 100 division on the circular scale. While measuring the diameter of a wire, the linear scale reads 1mm and 47th division on circular scale coincides with the reference line. The length of the wire is 5.6 cm. Find the curved surface area (in cm^2) of the wire in proper significant figures.

The pitch of a screw gauge is 1mm and its cap is divided into 100 divisions. When this screw gauge is used to measure the diameter of a wire, then main scale reading is 2 mm and 58^(th) division of circular scale coincides with the main scale. There is no zero error in the screw gage. Then the diameter of the wire is

The pitch of a screw gauge is 0.5mm and there are 50 divisions on its circular scale and one main scale division =0.5 mm. 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 4 division above the reference line. when a metallic wire is placed between the jaws, five main scale divisions are clearly visible and 18^(th) division on the circular scale coincides with the reference line. the diameter of the wire is

The pitch of a screw gauge is 0.55mm and there are 100 divisions on its circular scale. The instrument reads +2 divisions when nothing is put in between its jaws. In measuring the diameter of a wire, there are 8 divisions on the main scale and 83^(rd) division coincides with the reference. Then the diameter of the wire is
