A screw gauge gives the following reading when used to measure the diameter of a wire.

Main scale reading : $0\ mm$

Circular scale reading : $52\ divisions$

Given that $1\ mm$ on main scale corresponds to $100$ divisions of the circular scale. The diameter of wire from the above data is:

  • A$0.052$ $cm$
  • B$0.026$ $ cm$
  • C$0.005$ $ cm$
  • D$0.52$ $ cm$
