Experimental Physics Question 5

Question 5 - 2024 (30 Jan Shift 2)

If 50 Vernier divisions are equal to 49 main scal divisions of a travelling microscope and on smallest reading of main scale is $0.5 mm$, th Vernier constant of travelling microscope is:

(1) $0.1 mm$

(2) $0.1 cm$

(3) $0.01 cm$

(4) $0.01 mm$

Show Answer

Answer: (4)

Solution:

$50 V+S=49 S+S$

$S=50(S-V)$

$.5=50(S-V)$

$S-V=\frac{0.5}{50}=\frac{1}{100}=0.01 mm$
