NEET Physics Vernier Caliper MCQ Question
Which of the following statements about the Vernier Caliper is correct?
The least count is determined by the difference between one main scale division and one vernier scale division.
A positive zero error occurs when the zero of the vernier scale is to the left of the zero of the main scale.
The corrected reading is always obtained by subtracting the zero error from the observed reading.
Vernier Calipers can measure the internal diameter of hollow objects without requiring correction for zero error.
Correct Answer
Detailed Explanation
The least count is indeed defined as the difference between one main scale division and one vernier scale division. Positive zero error occurs when the vernier scale's zero lies to the right, and corrections depend on the type of zero error present.
