Assertion (A) : Screw gauge with a pitch...

Assertion (A) : Screw gauge with a pitch of `0.5mm` is more accurate then `1mm` for same number of circular scale divisions.
Reason (R ): Higher pitch can make the device more accurate.

A

Assertion is True, Reason is True, Reason is correct explanation for Assertion.

B

Assertion is True, Reason is True, Reason is not correct explanation for Assertion.

C

Assertion is True, Reason is False.

D

Assertion is False, Reason is True.

Text Solution

Verified by Experts

The correct Answer is:
C
`"Least count"=("Pitch")/("No. of circular scale divisions")`
So, less the pitch more will be the accuracy.
So, Assertion is true and reason is wrong.
