Assertion (A): Least count of all screw ...

Assertion (A): Least count of all screw based instruments is same.
Reason (R ): Least count for all screw based instruments are found using the ratio of pitch per division of circular scale.

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:
D
Assertion is false since it depends on the scale used. Reason is true by concept
