Question

Assume two arbitrary 3-D vectors A and B. Consider the vector given by the expresion Ax (Ax B).Which of the following statements for this vector is true? A. You can move parentheses around the cross products. Let's put them around A × A which evaluates to the zero vector. Thus A × (A x B) is equal to the zero vector. O B. You can move the parentheses ardand the double products. Let's put them around A x À which evaluates to A2 8 where A is the length of vector A.Thus Ax Ax B is equal to A B The direction of the vector representing the double product Àx (Ax B) is easily determined: It lie in the plane spanned by A and B and furthermore is perpendicular to A D. None of the statements above is correct

Explanation / Answer

All given statements are wrong for the cross product given so none of the statement given is correct.
