Question:medium

In an experiment with Vernier calipers of least count 0.1 mm, when two jaws are joined together the zero of Vernier scale lies right to the zero of the main scale and 6th 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 3.2 cm and 3.3 cm marks, and 4th division of Vernier scale coincides with the main scale division. The diameter of bob is measured as

Show Hint

Always remember: "Actual = Observed - (Zero Error)". If zero is to the right, error is positive (subtract). If zero is to the left, error is negative (effectively add).
