The angle between A vector +B vector and A vector × B vector is ________

Question

Sai Gopesh Rayudu Mellamputi · Answer

Geometrically, A + B yields a vector in the plane of A and B according to the parallelogram law of vector addition. Also, from the right hand thumb rule, cross product of the two vectors would be a vector out of their plane, and also perpendicular to each. So the angle between the two said expressions is a right angle.

Rajdeep · Answer

Considering two vectors A and B, the cross product is always perpendicular to the plane in which A, B and A+B lies. This can be found out by using the Right Hand Thumb Rule. Given: A x B Rules: Use your right hand. Place your hand along the direction of the first vector (here, A). Rotate your fingers along the smaller angle between A and B. The direction of your thumb will point outwards or inwards, which denotes perpendicular to the plane of the two vectors. Thanks!
