A screw gauge has a positive error of 4 division .When this screw gauge hold's sphere the main scale reading is 4 mm and the head scale coincinding division is 24 . If its least count is 0.01 mm find out he the volume of the sphere.

Pitch of the screw gauge is 0.5mm . Its head scale contains 50 divisions. The least count of it is

A screw gauge with a pitch of 1 mm has 100 divisions on its circular scale. What it is used to measure the diameter of a thin wire, the main scale reading is 3 mm and the circular scale reading is 45. If D is the diameter of the wire in mm, then find the value of D.

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

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

The pitch of a screw gauge is 1 mm with 100 divisions on the circular scale. For a given wire, the linear scale reads 2 mm and 64th divisions on the circular scale coincides with the reference line. If the length of the wire is 3.5 cm, find the volume in cm^(3) ?

A screw gauge has 1.0mm pitch and 200 divisions on the ciruclar scale. The least count of the instrument is

Two full turns of the circular scale of a screw gauge cover a distance of 1 mn on its its main scale . The total number of divisions on the circular scale is 50. Further m it is found that the screw gauge has a zero error of - 0.02 mm . While measuring the diameter of a thin wire , a student notes the main scale reading of 4 mm and the number of circular scale divisions in line with the main scale as 37. The diameter of the wire is

A vernier callipers has 20 divisions on the vernier scale which coincides with 19mm on the main scale. Its least count is
