Here is the diagram illustrating the two vectors. The first one is vector $\vec{a}$ with a magnitude of 2, and the second one, $\overline{a} + \overline{b}$, shows how vector $\vec{b}$ is constructed through vector addition.

Let me know if you have any questions or need further clarification!

Here are 5 related questions you might find interesting:

1. How do you calculate the magnitude of a vector in general?
2. How is vector addition used in physics and engineering applications?
3. Can vector subtraction also be visualized geometrically, and how does it work?
4. How would you represent vector projections on different axes?
5. What are the properties of unit vectors and how are they useful?

Tip: When adding or subtracting vectors, always align the tail of one vector to the tip of the other to visualize the resultant vector effectively.
