Question

if a vector dot b vector and a vector cross's b vectors then a vector and b vector are​

Answer 1

Answer:

If dot product is zero it means vectors lie perpendicular to each other. If cross product is zero, it means vectors lie along the same or opposite direction. These both can simultaneously be true only if the vector is null vector. Thus statement 1 is true. Also, statement 2 is true but it does not explain statement 1.
