Explanation of Vernier Calipers Reading and Error:
Vernier calipers are used to measure the length, diameter, and thickness of objects with high accuracy. The instrument consists of two jaws, one of which is fixed, while the other is movable. The movable jaw is connected to a thin metallic strip that moves upward or downward based on the object's size. The reading of the Vernier caliper is taken by adding the main scale reading to the Vernier scale reading.
Reading of Vernier Calipers:
In this case, the reading of the Vernier caliper is 6.4 CM. The Vernier caliper scale division is coinciding with the main scale division. Therefore, the actual length of the beaker is 6.4 CM. The Vernier scale reading is taken by aligning the Vernier scale with the main scale and reading the smallest division on the Vernier scale that coincides with the main scale. In this case, the Vernier scale reading is 0. The main scale reading is 6.4 CM.
Error of Vernier Calipers:
The error of Vernier calipers is the difference between the actual length of the object and the measured length. The error can arise due to various reasons such as parallax error, zero error, and incorrect alignment of the Vernier scale with the main scale. In this case, the Vernier scale division is coinciding with the main scale division, which means there is no zero error. Therefore, the reading of the Vernier caliper is accurate, and there is no error.
Conclusion:
In conclusion, Vernier calipers are an essential instrument used in various fields such as engineering, science, and medicine. It is important to take accurate readings and avoid errors while using Vernier calipers. The reading of the Vernier caliper is taken by adding the main scale reading to the Vernier scale reading. The error can arise due to various reasons, and it is important to identify and correct them to ensure accurate readings.
