A) 0
B) \[-1\]
C) 1
D) 2
E) \[-2\]
Correct Answer: C
Solution :
Since\[\overrightarrow{a}\]is\[\bot \]to\[\overrightarrow{a}\times \overrightarrow{b}\] \[\Rightarrow \] \[\overrightarrow{a}.(\overrightarrow{a}\times \overrightarrow{b})=0\] \[\Rightarrow \] \[(2\hat{i}-3\hat{j}+p\hat{k}).(4\hat{i}+2\hat{j}-2\hat{k})\] \[\Rightarrow \] \[8-6-2p=0\Rightarrow p=1\]You need to login to perform this action.
