A) \[\vec{b},\,\vec{c}\]
B) \[\vec{a},\,\vec{b}\]
C) \[\vec{a},\,\vec{c}\]
D) \[\vec{a},\,\,\vec{b}\,,\vec{c}\]
Correct Answer: A
Solution :
Since, \[\vec{b}\times \vec{c}\] is a vector perpendicular to \[\vec{b},\vec{c}\]. Therefore \[\vec{a}\times (\vec{b}\times \vec{c})\] is a vector again in plane of \[\vec{b},\vec{c}\].You need to login to perform this action.
