Chapter 1: Q4 (page 14)

For the following figure, determine $\vec{A B}$ is the same $\vec{B A}$ or not.

Short Answer

Expert verified

No, $\vec{A B}$ is not the same $\vec{B A}$ .

Step by step solution

Step 1. Check the figure.

Consider the figure.

Step 2. Apply the concept of a ray.

A ray is a part of a line thathas one endpointand goes on infinitely in only one direction. It is represented by the one-headed arrow.

Thus, in a ray $\vec{A B}$ , is the endpoint of the ray and its direction is towards in B, and in a ray $\vec{B A}$ , B is the endpoint of the ray and its direction is towards in A.

Step 3. Step description.

Since both the ray $\vec{A B}$ and $\vec{B A}$ are in a different direction and represent two different rays, thus they are not the same.

Therefore, $\vec{A B}$ is not the same $\vec{B A}$ .
