Solution
Correct Answer:
Smallest increment measurable
The Least Count is the smallest value that can be measured accurately with an instrument.
- For a meter scale, it is 1 mm.
- For a vernier caliper, it is often 0.1 mm or 0.02 mm.
- For a screw gauge, it is often 0.01 mm.
- The precision of an instrument is inversly related to its least count.
This easy difficulty physics question is from the chapter experimental skills and error analysis, covering the topic of least count. It appeared in the 2025 exam.
