The least count of a metre scale is
Correct answer: C. 1 mm.
- A. 0.001 cm.
- B. 0.1 mm.
- C. 1 mm.
- D. 1 cm
Explanation
The least count of a measuring instrument is the smallest measurement that can be accurately read. For a standard meter scale, the smallest division is 1 millimeter (mm), making the least count 1 mm. Option A, 0.001 cm, suggests an unrealistic precision not possible with a regular meter scale. Option B, 0.1 mm, is also not achievable with a typical meter scale. Option D, 1 cm, is too large to be the least count, as meter scales have finer divisions.
