A) $\mathbf { u } = \mathbf { i }$
B) $\mathbf { u } = 8 \mathrm { i }$
C) $\mathbf { u } = 64 \mathbf { i }$
D) $\mathbf { u } = \frac { 1 } { 8 } \mathrm { i }$

Question

Quizplus · Accepted Answer

The unit vector in the direction of $\mathbf{v} = 8\mathbf{i}$ is found by dividing $\mathbf{v}$ by its magnitude. The magnitude of $\mathbf{v}$ is $8$, so the unit vector is $\frac{8\mathbf{i}}{8} = \mathbf{i}$.
