Question:
Which of the following is most accurate?
Which of the following is most accurate?
Show Hint
Smaller the least count, higher is the accuracy of the instrument.
Updated On: Mar 17, 2026
- A screw gauge of least count 0.001 mm.
- A screw gauge having pitch 1 mm and 50 divisions on circular scale.
- A vernier calipers of least count 0.01 mm.
- Vernier calipers having 20 divisions on the sliding scale coinciding 19 divisions on the main millimeter scale.
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Accuracy depends on least count.
Step 2: Least count of option (A) is explicitly given as 0.001 mm, which is the smallest among all.
