When a vernier caliper ( least count 0.01 cm) was checked for zero error, the zero mark on the vernier scale was found towards the right and its third mark was in line with some mark on the main scale. When the instrument was used to determine the diameter of a given bob, the main scale reading was 2.1 cm and the sixth division was found to be coinciding with some division on the main scale. Calculate its zero error and corrected diameter of the given bob.
