The main scale of a vernier callipers reads in millimeter and its vernier is divided into 10 divisions which coincides with 9 divisions of the main scale. The reading for shown situation is found to be 12 x 10 ~mm . Find the value of x .

Correct answer

6

Step-by-step solution

aligned & Least count = 1 ~mm 10 =0.1 ~mm ; Zero error =-(10-6) 0.1=-0.4 ~mm & Reading =6+5 (0.1)-(-0.4)=7.2 ~mm aligned
