Vedclass · Answer

(C) The cross product of two vectors $\vec{A}$ and $\vec{B}$ is defined as $\vec{A} 	imes \vec{B} = AB \sin 	heta \; \hat{n}$,where $\hat{n}$ is the unit vector perpendicular to both $\vec{A}$ and $\vec{B}$.From this definition,we can isolate the unit vector $\hat{n}$ as:$\hat{n} = \frac{\vec{A} 	imes \vec{B}}{AB \sin 	heta}$.Since $|\vec{A}| = A$ and $|\vec{B}| = B$,the expression becomes $\frac{\vec{A} 	imes \vec{B}}{|\vec{A}| |\vec{B}| \sin 	heta}$.Thus,option $C$ is correct.

Which of the following is the unit vector perpendicular to $\vec{A}$ and $\vec{B}$?
