Direction ratios of the line perpendicular to the lines \(\frac{x+2}{1}=\frac{y+3}{2}=\frac{z-5}{-2}\) and \(\frac{x-3}{2}=\frac{y+7}{-3}=\frac{z-2}{1}\) are:
- A \(\langle 4,-5,7\rangle\)
- B \(\langle-4,5,7\rangle\)
- C \(\langle 4,5,-7\rangle\)
- D \(\langle 4,5,7\rangle\)
Answer & Solution
Correct Answer
(D) \(\langle 4,5,7\rangle\)
Step-by-step Solution
Detailed explanation
Direction ratios of the first line: \( \vec{d_1} = \langle 1, 2, -2 \rangle \) Direction ratios of the second line: \( \vec{d_2} = \langle 2, -3, 1 \rangle \) Direction ratios of the perpendicular line:…
