Chapter 14.2, Problem 3WE

To determine

To find: The representation of the given vector in the component form.

Answer to Problem 3WE

The component form is $-5i$ .

Explanation of Solution

Given:

The $\overrightarrow{QR}$ vector is to identified.

The given diagram is shown in Figure 1

  

Figure 1

Calculation:

From the given graph, the vector $\overrightarrow{QR}$ is obtained as,

Move 5 unit to the left on the x axis so it is -5i, the value on the y axis does not change there the value for j do not exist

The component form is $-5i$ .
