A) Zero
B) Only negative real number
C) Only positive real number
D) Every real number
Correct Answer: D
Solution :
\[\overrightarrow{AB}=\lambda \overrightarrow{BC}\], (for collinearity) Here \[\overrightarrow{AB}=-2\mathbf{b},\] \[\overrightarrow{BC}=(k+1)\mathbf{b}\] Hence \[\forall \,\,k\in R\Rightarrow \overrightarrow{AB}=\lambda \overrightarrow{BC}.\]You need to login to perform this action.
