વર્નિયર કેલીપર્સમાં, 50 વર્નિયર સ્કેલના વિભાગો (કાપા) બરાબર 48 મુખ્ય સ્કેલના વિભાગો છે. જો એક મુખ્ય સ્કેલના વિભાગ = 0.05 mm, તો વર્નિયર કેલીપર્સનું લઘુત્તમ માપ __________ mm છે.

A 0.002
B 0.05
C 0.02
D 0.005

Verified Solution

Answer & Solution

Correct Answer

(A) 0.002

Step-by-step Solution

Detailed explanation

\(LC =1 MSD -1 MSD =1 MSD -\frac{48}{50} MSD\) \(=\frac{2}{50} MSD =\frac{2}{50} \times .05 mm=0.002 mm\)

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
