JEE Main2010MathematicsThree Dimensional GeometryActual
Statement-1: The point A(3,1,6) is the mirror image of the point B(1,3,4) in the plane x-y+z=5 . Statement-2: The plane x-y+z=5 bisects the line segment joining A(3,1,6) and B(1,3,4) .
Options
- AStatement-1 is true, Statement-2 is true; Statement-2 is not the correct explanation for Statement-1
- BStatement-1 is true, Statement-2 is false
- CStatement-1 is false, Statement-2 is true
- DStatement-1 is true, Statement-2 is true; Statement-2 is the correct explanation for Statement-1
Correct answer
A. Statement-1 is true, Statement-2 is true; Statement-2 is not the correct explanation for Statement-1
Step-by-step solution
A(3,1,6) ; B=(1,3,4) Mid-point of A B=(2,2,5) lies on the plane. and d.r's of A B=(2,-2,2) d.r's Of normal to plane =(1,-1,1) . AB is perpendicular bisector A is image of B Statement-2 is correct but it is not correct explanation.
