Consider the two vectors A with arrow = 3 î − ĵ and B with arrow = − î − 2 ĵ. (a) Calculate A with arrow + B with arrow 2 Correc

Verdich [7]

Answer:

Let $\vec{A}=3\hat{i}-\hat{j}$ and $\vec{B}=-\hat{i}-2\hat{j}$ .

$\vec{A}+\vec{B}=(3\hat{i}-\hat{j})+(-\hat{i}-2\hat{j})=2\hat{i}-3\hat{j}$

$\vec{A}-\vec{B}=(3\hat{i}-\hat{j})-(-\hat{i}-2\hat{j})=4\hat{i}+\hat{j}$

c) Now we calculate the direction of $\vec{A}+\vec{B}$ and $\vec{A}-\vec{B}$

We calculate the direction of $\vec{A}+\vec{B}$ like this:

$\theta=tan^{-1}(\frac{-3}{2})=-56,3^{\circ}$ . Since, $270\leq\theta\leq360$ , then the direction of $\vec{A}+\vec{B}$ is $360^{\circ}-\theta=360^{\circ}-56.3^{\circ}=303.7^{\circ}$ .

Now, for $\vec{A}-\vec{B}$

$\theta=tan^{-1}(\frac{1}{4})=14^{\circ}$ .
