-$$\mathbf { v } = 7 \mathrm { i }$$
A) $\mathbf { u } = 49 \mathrm { i }$
B) $\mathbf { u } = 7 \mathbf { i }$
C) $\mathbf { u } = \frac { 1 } { 7 } \mathrm { i }$
D) $\mathbf { u } = \mathrm { i }$

Question

Quizplus · Accepted Answer

A unit vector in the direction of $\mathbf{v} = 7\mathbf{i}$ is obtained by dividing $\mathbf{v}$ by its magnitude, which is 7, resulting in $\mathbf{u} = \frac{7}{7}\mathbf{i} = \mathbf{i}$.
