A plane inclined at angle \(\theta\) has a velocity ratio of 10 : 1. The inclination of the plane to the horizontal is given by
- A. tan\(\theta\) = \(\frac{1}{10}\)
- B. cot\(\theta\) = \(\frac{1}{10}\)
- C. cos\(\theta\) = \(\frac{1}{10}\)
- D. sin\(\theta\) = \(\frac{1}{10}\)
Correct Answer: D. sin\(\theta\) = \(\frac{1}{10}\)
Explanation
V.R = \(\frac{1}{sin\theta}\)
= 10
sin = \(\frac{1}{10}\)
