Question

The smallest division on main scale of a vernier caplliers is 1 mm and 10 vernier divisions coincide with 9 main scale divisions. While measuring the length of a line, the zero mark of the vernier scale lies between 10.2 cm and 10.3 cm and the third division of vernier scale coincides with a main scale division. (a) Determine the least count of the callopers. (b) Find the length of the line.

Answer 1

The least count of vernier callipers is 0.01cm and The length of the line is 10.23cm

• According to the problem

 1MSD= 1mm

 MSR = 10.2cm

• Here 10VSD = 9MSD

          1VSD = (9/10)MSD

                    =(9/10)×1mm = (9/10)mm

• Least count of vernier callipers L.C =1MSD - 1VSD

                                                          =1mm - (9/10)mm

                                                          =0.01mm

                                                 L.C   =0.01cm

• Length of the line = MSR+(VSD×L.C)

                             =10.2+(3×0.01)

                             =10.2+(0.03)p

                             =10.23 cm
