બિંદુ \(P\left( {1, - 2,3} \right)\) નું સમતલ \(2x + 3y - 4z + 22 = 0\) માં રેખા \(\frac{x}{1} = \frac{y}{4} = \frac{z}{5}\) ની સાપેક્ષે પ્રતિબિંબ જો \( Q\)  હોય તો \(PQ \) મેળવો.

  1. A \(6\sqrt 5 \)
  2. B \(3\sqrt 5 \)
  3. C \(2\sqrt {42} \)
  4. D \(\sqrt {42} \)
Verified Solution

Answer & Solution

Correct Answer

(C) \(2\sqrt {42} \)

Step-by-step Solution

Detailed explanation

\(\text { Equation of line } \mathrm{PQ} \text { is } \frac{x-1}{1}=\frac{y+2}{4}=\frac{z-3}{5}\) \(\text { Let } \mathrm{F} \text { be }(\lambda+1,4 \lambda-2,5 \lambda+3)\) Since Flies on the plane \(\therefore 2(\lambda+1)+3(4 \lambda-2)-4(5 \lambda+3)+22=0\)…
