Match List-I with List-II regarding the types of errors in measurement:
Choose the correct answer from the options given below:
| List-I | List-II |
|---|---|
| (A) Zero error of vernier calipers | (I) Imperfection in experimental technique |
| (B) Ignoring buoyancy of air while weighing | (II) Random error |
| (C) Parallax in reading a scale | (III) Instrumental error |
| (D) Unpredictable mechanical vibrations | (IV) Personal error |
Choose the correct answer from the options given below:
Options
- A(A)-(III), (B)-(IV), (C)-(I), (D)-(II)
- B(A)-(II), (B)-(I), (C)-(IV), (D)-(III)
- C(A)-(III), (B)-(I), (C)-(IV), (D)-(II)
- D(A)-(I), (B)-(III), (C)-(IV), (D)-(II)
Correct answer
C. (A)-(III), (B)-(I), (C)-(IV), (D)-(II)
Step-by-step solution
Zero error of vernier calipers arises from built-in defects of the measuring instrument, hence it is an instrumental error (A-III).
Ignoring the buoyancy of air while weighing a body is a flaw in the experimental procedure, which is an imperfection in experimental technique (B-I).
Parallax in reading a scale occurs due to an individual's improper setting of the apparatus or carelessness in taking observations, making it a personal error (C-IV).
Unpredictable mechanical vibrations cause irregular fluctuations in the setup, leading to random errors (D-II).
Therefore, the correct matching is (A)-(III), (B)-(I), (C)-(IV), (D)-(II).
Answer: (A)-(III), (B)-(I), (C)-(IV), (D)-(II)
