Question

What is the magnitude of the force F⃗ on the -10 nC charge in the figure(Figure 1) ?

Answer 1

I don't see a figure

Answer 2

What was your approach to the question?

Answer 3

Magnitude of the force on the -10nC charge will be the sum of the forces on that charge. Each individual force can be calculated using Coulomb's Law:\[F=\frac{ 1 }{ 4\pi \epsilon _{0} }\frac{ q _{1} q _{2}}{ r ^{2} }\]
