A) \[-5\]
B) 4
C) 5
D) \[-4\]
E) \[-7\]
Correct Answer: C
Solution :
Now, \[\overrightarrow{A}+t\overrightarrow{B}=(1-t)\hat{i}+(2+2t)\hat{j}+(3+t)\hat{k}\] \[(\overrightarrow{A}+t\overrightarrow{B}).\overrightarrow{C}=3(1-t)+2+2t=0\] \[\Rightarrow \]\[-3t+2t+3+2=0\] \[\Rightarrow \]\[-t=-5\]\[\Rightarrow \]\[t=5\]You need to login to perform this action.
