A printed page is kept pressed by a glass cube (\(\mu = 1.5\)) of 5 cm edge. By what amount will the printed letters appear to be shifted when viewed from the top?
- A 2 cm
- B 1 cm
- C \(1.7 cm\)
- D \(2.5 cm\)
Answer & Solution
Correct Answer
(C) \(1.7 cm\)
Step-by-step Solution
Detailed explanation
Shift \( = t \left(1 - \frac{1}{\mu}\right)\) Shift \( = 5 \left(1 - \frac{1}{1.5}\right)\) Shift \( = 5 \left(1 - 0.666...\right)\) Shift \( = 5 \left(0.333...\right)\) Shift \( = 1.666...\) cm Shift \( \approx 1.7 \) cm
