In an experiment with vernier calipers of least count $\displaystyle 0.1$ mm , when two jaws are joined together the zero of vernier scale lies right to the zero of the main scale and $\displaystyle 6$ th division of vernier scale coincides with the main scale division. While measuring the diameter of a spherical bob, the zero of vernier scale lies in between $\displaystyle 3.2$ cm and $\displaystyle 3.3$ cm marks, and 4th division of vernier scale coincides with the main scale division. The diameter of bob is measured as
