When circular scale of a srew gauge carr...

When circular scale of a srew gauge carrying `100` divisions is given four complete rotations, the head of the screw moves through `2mm`. The pitch and least count of screw gauge are respectively.

A

0.005 cm

B

0.0005 cm

C

0.001 cm

D

0.0001 cm

Text Solution

Verified by Experts

The correct Answer is:
B
`"Pitch"= (2)/(4) mm= (1)/(2) mm= (1)/(20) cm`
`L.C. = ("Pitch")/(100)= (1)/(2000) cm= 0.0005 cm`
