A) \[0\]
B) \[1\]
C) \[|\vec{r}|\]
D) \[2|\vec{r}|\]
Correct Answer: C
Solution :
Given, \[|\vec{u}|=|\vec{v}|=1\] and \[\vec{u}\,.\,\vec{v}=0\] ie, angle between \[\vec{u}\] and \[\vec{v}\] is \[{{90}^{o}}\] \[\therefore \] \[\vec{u}\times \vec{v}=|\vec{u}||\vec{v}|\,\sin \theta =1\]You need to login to perform this action.
