Explanation
Solution
The main scale reading (MSR) is 6 mm. The Vernier scale division that aligns with a main scale division is the 10th division. The least count (LC) of the Vernier caliper is 0.1 mm. Therefore, the Vernier scale reading (VSR) is 10 * 0.1 mm = 1 mm. The total reading is MSR + VSR = 6 mm + 1 mm = 7 mm.
