The mirror image of the point (1, 2, 3) ...

The mirror image of the point (1, 2, 3) in a plane is (-1,2,-3) . Which of the following points lies on this plane?

A

`(0,1,2)`

B

`(0,2,0)`

C

`(0,2,1)`

D

`(1,-1,1)`

Text Solution

Verified by Experts

The correct Answer is:
B

Point on plane R (0,2,0)
Normal vector of plane is `hati + 3hatk`
Equation of required plane is `x + 3z =0`
Hence (0,2,0) lies on plane
