A screw gauge gives the following reading when used to mesure the diametre of a wire.
Main scale reading : `0mm`
Circular scale reading : `52 divisions`
Given that `1mm` on main scale corresponds to `100` divisions of the circular scale. the diameter of wire from the above data is :

A

0.52 cm

B

0.052 cm

C

0.026 cm

D

0.005 cm

Text Solution

Verified by Experts

The correct Answer is:
B
L.C. `= 1/100` mm=0.01mm
Diameter = Division of circular scale `xx` (L.C.) + Main scale reading
`implies 52xx0.01+0=0.52 mm=0.052cm.`

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
