In this video we try to find vectors perpendicular to a pair of given vectors. Since cross products give exactly this, we take the cross product of given vectors. Additionally, if we want to find the unit vectors, we divide the cross product by its magnitude. We also solve a problem where the dot product of the perpendicular is given and we have to find the missing vector. Note - in general, there are two vectors perpendicular to two given vectors - both opposite of each other.
