A screw gauge gives the following reading when used to measure the diameter of a wire .
Main scale reading : 0 mm
Circular scale reading : 52 division
Given that 1 mm on main scale corresponds to 100 divisions of the circular scale.
The diameter of wire from the above data is :
Text Solution
Verified by ExpertsThe correct answer is:
B
Least count of screw gauge = 
= 0.01 mn
Diameter - Divisions on cirular scale × least count + main scale reading
= 52 × 
= 0.52 mm
diameter = 0.052 cm
