Vernier Callipers Puzzles
1. What is the least count of a Vernier Callipers?
Hint: It is the smallest measurement the instrument can measure.0.01 cm (or 0.1 mm)
2. What are the two scales present in a Vernier Callipers?
Hint: One is fixed, and the other moves.Main Scale and Vernier Scale
3. What is the purpose of the lower jaws of Vernier Callipers?
Hint: They measure an object's external dimensions.To measure the external diameter or length of an object.
4. What is the function of the upper jaws of Vernier Callipers?
Hint: They measure an object's internal dimensions.To measure the internal diameter of a hollow object.
5. What is the function of the depth rod in Vernier Callipers?
Hint: It is used for measuring the depth of an object.To measure the depth of holes or recesses.
6. How many divisions on the Vernier Scale coincide with a certain number of Main Scale divisions?
Hint: Usually, 10 Vernier Scale divisions match a certain number of Main Scale divisions.10 Vernier Scale divisions coincide with 9 Main Scale divisions.
7. What is zero error in Vernier Callipers?
Hint: It occurs when the zero marks do not align.A systematic error occurring when the zero mark of the Main Scale does not coincide with the zero mark of the Vernier Scale.
8. How do you correct a positive zero error in Vernier Callipers?
Hint: You need to subtract the zero error from the final reading.Subtract the zero error from the final reading.
9. What is the range of Vernier Callipers commonly used in laboratories?
Hint: It is usually between 10 cm to 30 cm.Usually 10 cm to 30 cm.
10. What is the principle of a Vernier Callipers?
Hint: It uses the difference between the Main Scale and Vernier Scale readings.It works on the principle of least count, which is the difference between one Main Scale division and one Vernier Scale division.
