Solution

Pitch is the linear distance traveled by one complete rotation of circular scale.
Since 1 division is traveled in main scale, so the pitch will be $1 m m$ .

The pitch of a screw gauge is 1 mm and there are 100 division on the circular scale. A students measures a diameter of a wire using this screw gauge and he gets main scale reading as 5 mm and circular divisions as 25. If the screw gauge has positive zero error $0.03 m m$ , the correct value of diameter will be
