यदि रेखाओं \(\frac{x-\lambda}{3}=\frac{y-2}{-1}=\frac{z-1}{1}\) और \(\frac{x+2}{-3}=\frac{y+5}{2}=\frac{z-4}{4}\) के बीच की न्यूनतम दूरी \(\frac{44}{\sqrt{30}}\), है तो \(|\lambda|\) का अधिकतम संभावित मान .......... है।

  1. A \(45\)
  2. B \(49\)
  3. C \(43\)
  4. D \(40\)
Verified Solution

Answer & Solution

Correct Answer

(C) \(43\)

Step-by-step Solution

Detailed explanation

\( \overline{\mathrm{a}}_1=\lambda \hat{\mathrm{i}}+2 \hat{\mathrm{j}}+\hat{\mathrm{k}} \) \( \overline{\mathrm{a}}_2=-2 \hat{\mathrm{i}}-5 \hat{\mathrm{j}}+4 \hat{\mathrm{k}} \) \( \overrightarrow{\mathrm{p}}-=3 \hat{\mathrm{i}}-\hat{\mathrm{j}}+\hat{\mathrm{k}} \)…
