A micrometer screw gauge is used to determine the diameter of a copper wire. Diagram 1 shows the reading when the wire is in place. The wire is then taken out and the jaws of the micrometer are closed. Diagram 2 shows the new reading. What is the diameter of the wire?
- A$1.90\,\text{mm}$
- B$2.45\,\text{mm}$
- C$2.59\,\text{mm}$
- D$2.73\,\text{mm}$
