A) (3,-4, -2)
B) (5,-8,-4)
C) (1,-1,-10)
D) (2, -3, 8)
Correct Answer: B
Solution :
Q is reflection of P w.r.t. to given line L. Let Q is \[(\alpha ,\beta ,\gamma )\]then \[(\alpha ,\beta ,\gamma )\]lies on then line \[\Rightarrow \]\[\frac{\frac{\alpha +1}{2}-1}{2}=\frac{\frac{\beta }{2}+1}{-3}=\frac{\frac{\gamma }{2}+10}{8}=\lambda \]and\[2(\alpha -1)-3\beta +8\gamma =0\]\[\Rightarrow \]\[\alpha =5,\beta =-8,\gamma =-4.\]You need to login to perform this action.
