# Problem: What is the force F on the 1 nC charge at the bottom? (Figure 1) Write your answer as two vector components, separated by a comma. Express each component numerically, in newtons, to three significant figures.

###### FREE Expert Solution

In this problem, we're going to use Coulomb's law to determine the force acting on 1 nC charge at the bottom.

Coulomb's law:

$\overline{){\mathbf{F}}{\mathbf{=}}\frac{\mathbf{k}{\mathbf{q}}_{\mathbf{1}}{\mathbf{q}}_{\mathbf{2}}}{{\mathbf{r}}^{\mathbf{2}}}}$, where F is the force between two charges q1 and q2, r is the distance between the two charges, and k is Coulomb's constant.
