Q1 Single Correct Medium
To measure the diameter of a wire, a screw gauge is used. In a complete radiation, spridle of the screw gauge advances by $$\frac{1}{2}$$ mm and its circular scale has 50 deviations. The main scale a graduated to $$\frac{1}{2}$$mm. If the wire is put between the jaws, 4 main scale divisions are clearly visible and 1 dimensions of circular scale co-inside with the reference line. The resistance of the wire is measured to be  $$(10\Omega \pm 1%)$$. Length of eh wire is measured to be 10 cm using a scale of least circuit 1 mm. Maximum permissible error in resistivity measurement is:
  • A. 1.5%
  • B. 2%
  • C. 2.9%
  • D. 3%
