A) - 2
B) - 1
C) 1
D) 2
Correct Answer: D
Solution :
The matrix \[A=\left[ \begin{matrix} \,\,0 & \,\,1 & -2 \\ -1 & \,\,0 & \,\,3 \\ \,\,\lambda & -3 & \,\,0 \\ \end{matrix} \right]\] is singular Þ \[|A|\] = 0 Þ \[0-1(-3\lambda )+(-2)(3)=0\] \[\Rightarrow 3\lambda -6=0\Rightarrow \lambda =2\].You need to login to perform this action.
