What is Coulomb's Law and what are the initial conditions for a charge q1?

Step 1: Analyze Question 1.
The electrostatic force $\vec{F}$ on charge $q_2$ at $\vec{r_2}$ due to charge $q_1$ at $\vec{r_1}$ is given by Coulomb's Law:

$$\vec{F} = \frac{1}{4\pi\epsilon_0} \frac{q_1 q_2}{|\vec{r_2} - \vec{r_1}|^3} (\vec{r_2} - \vec{r_1})$$

Given:

• Position of $q_1$: $\vec{r_1} = (2\hat{i} + 2\hat{j} + \hat{k})$
