Answer 2

Answer:

Reversing the order of cross multiplication reverses the direction of the product. Since two identical vectors produce a degenerate parallelogram with no area, the cross product of any vector with itself is zero…

Step-by-step explanation:

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 zeIf A and B are two vectors, then A cross B is not equal to B cross A.ro (θ = 0°   or θ = 180° and sin θ = 0). 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.
