I'll mark ans as brainliest one​

Answer 1

Answer:

If the cross product of two vectors is the zero vector (i.e. a × b = 0), then either one or both of the inputs is the zero vector, (a = 0 or b = 0) or else they are parallel or antiparallel (a ∥ b) so that the sine of the angle between them is zero (θ = 0° or θ = 180° and sinθ = 0).

Answer 2

So let the two vectors be A and B

Now we know that

Cross product of A and B =

ABsinTHETA

0 = ABsinTHETA

Sin theta = 0

Therefore the angle THETA = 0° or 180°
