Let Q be the mirror image of the point P (1,0,1) with respect to the plane S: x+y+z=5. If a line L passing through (1, -1, -1), parallel to the line…
Let Q be the mirror image of the point $\displaystyle \mathrm{P}(1,0,1)$ with respect to the plane $\displaystyle \mathrm{S}: x+y+z=5$. If a line L passing through ($\displaystyle 1$, -$\displaystyle 1$, -$\displaystyle 1$), parallel to the line PQ meets the plane S at R, then $\displaystyle \mathrm{QR}^2$ is equal to :
