Question

If the distance is measured in kilometer scale then the maximum permissible error will be :

• A. ${10}^{-3}$ on mm scale
• B. ${10}^6$ on mm scale
• C. ${10}^3$ on mm scale
• D. ${10}^7$ on mm scale

Answer 1

The correct option is B ${10}^6$ on mm scale

Maximum possible error is the LC of a scale .

Hence, maximum possible error is 1 km, which is same as the reading of ${10}^6$ on an mm scale.
