NEET Physics Vernier Caliper Assertion Reason Question
Assertion (A): A positive zero error in Vernier Calipers results in measurements being recorded higher than the actual value. | Reason (R): The zero of the vernier scale is shifted to the right of the zero of the main scale, necessitating a correction.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true, but R is false.
A is false.
Correct Answer
Detailed Explanation
The NCERT context explains that a positive zero error occurs when the zero of the vernier scale is shifted to the right, causing the measurement to be higher than actual, thus requiring a correction.
