NEET Physics Screw Gauge Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 12
Assertion (A): The least count of a screw gauge depends on the number of divisions on the circular scale. | Reason (R): The linear distance moved by the screw for one division of the circular scale is the least count of the screw gauge.
A
Both A and R are true and R is the correct explanation of A.
B
Both A and R are true, but R is not the correct explanation of A.
C
A is true, but R is false.
D
A is false, but R is true.
