(A) \(2 x-y+3 z+7=0\)
(B) \(3 x-y+2 z+7=0\)
(C) \(3 x-y+2 z=7\)
(D) \(3 x+y+2 z=7\)
View Dynamic Solution & Explanation
Correct Solution: Option C

Step-by-step Solution:

Equation of the plane passing through \((1,2,3)\) and having the vector \(\bar{N}=3 i-j+2 k\) as its normal is \[\] \(\Rightarrow 3(x-1)+-1(y-2)+2(z-3)=0\) \[\] \(\Rightarrow 3 x-y+2 z-3+2-6=0\) \[\] \(3 x-y+2 z=7\) \[\] Choice (C)
