Answer 2

Answer:

Explanation:

C=AB sin θ

The direction of vector C is perpendicular to both A and B and is therefore perpendicular to the plane defined by A and B. There are, however, two possible directions perpendicular to this plane. We remove this ambiguity by using the right-hand rule. As shown in Figure 2.31, let the fingers of your right hand curl from the first vector A to the second vector B through the smaller angle joining them. Your thumb will then give the direction of C, perpendicular to both A and B. If A and B both lie in the x−y plane, as shown in Figure 2.32, the vector product C = A × B will be in the z- direction.
