JEE Main 2020 — Three Dimensional Geometry Question with Solution

JEE Main 2020 (07 Jan Shift 1)

Question

Let P be a plane passing through the points 2,1,0,4,1,1 and 5,0,1 and R be any point 2,1,6 .Then the image of R in the plane P is

Choose an option

Show full solutionCorrect option: B
Correct answer
B6,5,-2

Step-by-step explanation

Solving for Equation of Plane, we get, x+y-2z=3

Now applying relation to find Image of point about a Plane, we get,

x-21=y-11=z-6-2=-22+1-12-36⇒x,y,z=6,5,-2
