Let be the plane, passing through the point \left(1, - 1, - 5\right)P from
Options
- A
- B
- C
- D
Correct answer
C.
Step-by-step solution
Given,
be the plane, passing through the point \left(1, - 1, - 5\right) and perpendicular to the line joining the points \left(4, 1, - 3\right) and \left(2, 4, 3\right),
So, direction ratio of Plane Normal will be, \left(4 - 2, 1 - 4, - 3 - 3\right) ≡ \left(2, - 3, - 6\right)
Now, equation of Plane will be,
- 3 \left(y + 1\right) = 0⇒ 2x - 3y - 6z - 35 = 0
Hence, perpendicular distance of = \left|\dfrac{2 \times 3 - 3 \times - 6 \times 2 - 35}{\sqrt{{2}^{2} + {\left(- 3\right)}^{2} + {\left(- 6\right)}^{2}}}\right| = \left|\dfrac{6 + 6 - 12 - 35}{\sqrt{{2}^{2} + {\left(- 3\right)}^{2} + {\left(- 6\right)}^{2}}}\right| = 5
