(adsbygoogle = window.adsbygoogle || []).push({}); [SOLVED] Electric Field Question

1. The problem statement, all variables and given/known data

2. Relevant equations

[tex]\frac{Q}{4\eta\epsilon_{o}\\r^{2}}[/tex]

Weight = (m)(g)

3. The attempt at a solution

I broke uo the forces into [tex]F_{r}[/tex] (the force of repulsion), the weight and normal contact force. I get stuck after that and would appreciate any helpful hints. (Ignore any pencil marks on the question)

Thanking you in advance.
