10. In which part of the Vernier caliper is used to measure the internal diameter of a cylindrical pipe?

11. Define length.

12. 5 x 3 = 15
13. What is the measuring unit of the thickness of a plastic carry bag?

14. How will you measure the least count of vernier caliper ?

15. The mass of an object is 5 kg. What is its weight on the earth?

16. While measuring the diameter of an iron nail using a screw gauge, the reading on the pitch scale is found to be 1.5 mm and the head scale reading is 20. If the least count is 0.01 mm and the zero error is + 0.05 mm, find the diameter of the iron nail.

17. The Main scale reading is 3.8 Vernier scale coincidence = 5th division. No zero error. Find the length of the iron cylinder.

18. 2 x 5 = 10
19. Calculate the positive and negative error from the given figure

20. Find the diameter of a thin wire using screw gauge.
