Question

What is the angle between c*d and c+d vector
O 0
0°
O
45°
O 60°​

Answer 1

90° or π/2 radians

Explanation:

The vector a=c+d lies in the plane of vectors c and d. By definition, the cross product of c and d lies in the plane perpendicular to both these vectors. Thus, (c+d)⊥(c×d)

Answer 2

Answer:

90°

Explanation:

Vector C = Vector A + Vector B. So, the vector C is now in the same plane as A and B. Now Vector D is the cross product of A and B. So, imagine A and B are two vectors in the same plane. Their cross product will give you a vector perpendicular to the plane. Like a normal. So vector C and D are perpendicular to each other
