If AxB= 2 3 4 / 1 5 2 then vector B is:
Correct answer: B. i+5j + 2k
- A. 2i + 3j + 4k
- B. i+5j + 2k
- C. -142+7k
- D. 2i+5j+4k
Explanation
IT is incorrect as it shows the vector A. It represents the vector b {i+5j+2k}

About Vector Product
The vector product, or cross product, gives a vector perpendicular to two multiplying vectors, with magnitude AB sin θ and direction set by the right-hand rule. It covers properties such as anti-commutation, area from cross products, torque and angular momentum. Unlike the dot product, its result is a vector.
