How are the pitch and least count of a spherometer related ?

A

`"Pitch" = (L.C.)/(100)`

B

`L.C. = ("Pitch")/(100)`

C

`"Pitch" = (L.C. xx 200)`

D

`L.C. = ("Pitch")/("number of divisions on circular scale")`

Text Solution

Verified by Experts

The correct Answer is:
D
`L.C. = ("Pitch")/("number of divisions on circular scale")`
