On the basis of details given about two measuring instruments, select the correct statement:
(i) Vernier callipers having main scale division = 0.05 cm and vernier scale division = 2.4550cm
(ii) Screw gauge having pitch 0.5 mm and its circular scale has 50 divisions
Consider a Vernier calipers in which each 1 cm on the main scale is divided into 8 equal divisions and a screw gauge with 100 divisions on its circular scale. In the Vernier callipers, 5 divisions of the Vernier scale coincide with 4 divisions on the main scale and in the screw gauge, one complete rotation of the circular scale moves it by two divisions on the linear scale. Then
Least count/hop count of main scale of a vernier callipers is defined as:
