A) 11i ? 6j ? k
B) ? 11i + 6j + k
C) 11i ? 6j + k
D) ? 11i + 6j ? k
Correct Answer: B
Solution :
\[\overrightarrow{A}=2i+3j+4k\] and \[\overrightarrow{B}=i+j+5k\] \[\overrightarrow{A},\,\overrightarrow{B}\] and \[\overrightarrow{C}\] form a left or right handed system according as \[[\overrightarrow{A}\,\overrightarrow{B}\,\overrightarrow{C}]<0\] or \[>0\] respectively. Here, \[[\overrightarrow{A}\,\overrightarrow{B}\,\overrightarrow{C}]<0\], \ \[\overrightarrow{C}=-11i+6j+k.\]You need to login to perform this action.
