Main scale of a vernier callipser has 100 divisions in 5 cm . Its vernier scale has 25 divisons in one cm . The least count is -

A

`0.01` cm

B

`0.005` cm

C

`0.01` mm

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
MSD = 5/100 = `.05` cm `implies` VSD = 1/25 = `.04` cm
`therefore` LC = MSD - VSD = `.01` cm
