Fig. 10.1 shows a measuring scale which is usually supplied with a geometry box. Which of the following distance cannot be measured with this scale by using it only once?
(a) 0.1 m
(b) 0.15 m
(c) 0.2 m
(d) 0.05 m
This scale is 0.15 m long. 0.2 m cannot be measured, if used only once.
Hence option (C) is correct.
