Question

1. I Trace the vectors in FIGURE EX3.1 onto your paper. Then find

(a) $\overrightarrow{A}+\overrightarrow{B}$and (b) $\overrightarrow{A}-\overrightarrow{B}$

Short answer

Part (a)

Part (b)

Step-by-step solution

Part (a)

Let $\overrightarrow{R}$be the resultant vector. Join the tail of $\overrightarrow{B}$with the head of$\overrightarrow{A}$ :

The resultant vector of$\overrightarrow{A}$ and$\overrightarrow{B}$ is

Part (b)

Let $\overrightarrow{R}$be the resultant vector. Join the tail of $\overrightarrow{B}$with the head of$\overrightarrow{A}$:

The resultant vector of and is
