A micrometer screw has a pitch of 0.5 mm. the circular scale is divided into 50 parts. The least ofmicrometer is

The pitch and the number of divisions, on the circular scale for a given screw gauge are 0.5 mm and 100 respectively. When the screw gauge is fully tightened without any object, the zero of its circular scale lies 3 division below the mean line. The readings of the main scale and the circular scale, for a thin sheet, are 4.5 mm and 48 respectively, the thickness of the sheet is:

The circular head of a screw gauge is divided into 50 divisions and the screw moves 2 mm ahead in one revolution of circular head. The least count of the screw gauge is0.001 cm0.002 cm0.004 cm0.005 cm

The whole length of a metre scale is divided into500 equal parts then the smallest measurementthat can be measured by using the scale is _______.(a) 0.5 m (b) 0.005 m(c) 50 mm (d) 2 mm

What is pitch of a screw gauge

A student measured the length of a rod and wrote it as 3.50 cm. Which instrument did he use to measure it :A meter scaleA vernier calliper where the 10 divisions in vernier scale matches with 9 divisions in main scale and main scale has 10 divisions in 1 cmA screw gauge having 100 divisions in the circular scale and pitch is 1 mmA screw gauge having 50 divisions in the circular scale and pitch is 1 mm
