A) (1, 2, 2)
B) \[(-1,\,2,\,-2)\]
C) (?3, 6, ?9)
D) \[(-1/3\,,\,2/3,\,-2/3)\]
Correct Answer: B
Solution :
Co-ordinates of P are \[(lr,\,mr,\,nr)\] Here\[l=\frac{-1}{\sqrt{{{1}^{2}}+{{2}^{2}}+{{2}^{2}}}}=\frac{-1}{3},\,m=\frac{2}{3},\,n=\frac{-2}{3}\] and \[r=3\,\], (given) \ Co-ordinates of P are (?1, 2, ?2).You need to login to perform this action.
