A) (2, - 4, 2)
B) (1, 1, 1)
C) (0, 0, 0)
D) (0, 0, 0)
Correct Answer: C
Solution :
\[\overline{n}={{\overline{n}}_{1}}\times {{\overline{n}}_{2}}\] \[=\left| \begin{matrix} {\hat{i}} & {\hat{j}} & {\hat{k}} \\ 6 & 7 & 8 \\ 3 & 5 & 7 \\ \end{matrix} \right|\] \[=(9,-18,9)\] \[=(1,-2,1)\] \[1(x+1)-2(y-1)+(2-3)=0\] \[=\]foot to z \[\frac{x-1}{1}=\frac{y+2}{-2}=\frac{z-1}{1}=\frac{[1+4+1]}{6}\] \[\]10,000You need to login to perform this action.
