બિંદુ \((1,-2,3)\) થી સમતલ \(x-y+z=5\) નું રેખા \(\frac{x}{2}=\frac{y}{3}=\frac{z}{-6}\) ને સમાંતર અંતર મેળવો 

  1. A \(7\)
  2. B \(1\)
  3. C \(\frac{1}{7}\)
  4. D \(\frac{7}{5}\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(1\)

Step-by-step Solution

Detailed explanation

equation of line parallel to \(\frac{x}{2}=\frac{y}{3}=\frac{z}{-6}\) passes \(\begin{array}{c}\text { through }(1,-2,3) \text { is } \\\frac{x-1}{2}=\frac{y+2}{3}=\frac{z-3}{-6}=r \\x=2 r+1 \\y=3 r-2 \\z=-6 r+3\end{array}\) So \(\quad 2 r+1-3 r+2-6 r+3=5\)…
