JEE Mains · Maths · STD 12 - 11. three dimension geometry

ધારો કે સમતલ \(P : 8 x+\alpha_1 y+\alpha_2 z+12=0\) એ રે ખા. \(L : \frac{x+2}{2}=\frac{y-3}{3}=\frac{z+4}{5}\) ને સમાંતર છે.જો \(P\)નો \(y-\) અક્ષ પરનો અંત:ખંડ \(1\) હોય,તો \(P\) અને \(L\) વચ્ચેનું અંતર \(..............\) છે.

  1. A \(\sqrt{14}\)
  2. B \(\frac{6}{\sqrt{14}}\)
  3. C \(\sqrt{\frac{2}{7}}\)
  4. D \(\sqrt{\frac{7}{2}}\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(\sqrt{14}\)

Step-by-step Solution

Detailed explanation

P: \(8 x+\alpha_1 y+\alpha_2 z+12=0\) \(L : \frac{ x +2}{2}=\frac{ y -3}{3}=\frac{ z +4}{5}\) \(\because\) \(P\) is parallel to \(L\) \(\Rightarrow 8(2)+\alpha_1(3)+5\left(\alpha_2\right)=0\) \(\Rightarrow 3 \alpha_1+5\left(\alpha_2\right)=-16\) Also \(y\)-intercept of plane…
