A screw gauge gives the following reading when used to measure the diameter of a wire. Main scale reading `=0mm`, circular scale reading `=52` divisions. Given that `1mm` on main scale corresponds to `100` divisions of the circular scale. The diameter of the wire from the above data is

A

0.026 cm

B

0.005 cm

C

0.52 cm

D

0.052 cm

Text Solution

Verified by Experts

The correct Answer is:
D
Least count `= (1 "mm")/(100)=0.01 mm`
Diamter of the wire `= 0 + 52 xx 0.01 mm = 0.52 mm = 0.052 cm`
