In a simple micrometer with screw pitch 0.5 mm and division on thimble 50, the reading corresponding to 5 divisions on barrel and 12 divisions on thimble is
- A. 2.620 mm
- B. 2.512 mm
- C. 5.120 mm
- D. 5.012 mm
Answer: A. 2.620 mm
Explanation: Least count = 0.5/50 = 0.01. Reading = 5(0.5) + 12(0.01) = 2.5 + 0.12 = 2.62 mm.
