The coordinates of the foot of the perpendicular drawn from a point \(\mathrm{P}(-1,1,2)\) to the plane \(2 x-3 y+z-11=0\)
- A \((2,-2,1)\)
- B \((2,-3,0)\)
- C \((1,-2,3)\)
- D \((4,1,6)\)
Answer & Solution
Correct Answer
(C) \((1,-2,3)\)
Step-by-step Solution
Detailed explanation
Equation of the line through \(\mathrm{P}(-1,1,2)\) and perpendicular to the plane \(2 x-3 y+z-11=0\): \(\frac{x-(-1)}{2} = \frac{y-1}{-3} = \frac{z-2}{1} = t\)
