Question

Trace the vectors in FIGURE EX3.2 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)

Place the tail of vector $\overrightarrow{B}$on the tip of vector $\overrightarrow{A}$and then connect the tail of vector $\overrightarrow{A}$with the tip of the vector $\overrightarrow{B}$as shown below

Part (b)

To find $\overrightarrow{A}-\overrightarrow{B}=\overrightarrow{A}+(-\overrightarrow{B})$, place the tail of vector $-\overrightarrow{B}$on the tip of vector $\overrightarrow{A}$and then connect the tail of $\overrightarrow{A}$vector with the tip of the vector $(-\overrightarrow{B})$as shown below:
