I'm having trouble cancelling out my units.
\[(N \cdot \cancel{m^2}/\cancel{C^2)}\left[\frac{\cancel{C}}{\cancel{m}^2}+\frac{\cancel{C}}{\cancel{m}^2}\right]\]
I've N left, but I should have N/C

nevermind I think I see my mistake, C^2 doesn't cancel out C

\(\frac{C}{m^2}+\frac{C}{m^2}=\frac{2C}{m^2}\)

The m's are different, I can't add them. \[8.99\times10^9N\cdot m^2/C^2\left[\frac{(5\times10^{6}C)}{(0.11m)^2}+\frac{(5\times10^6C)}{(0.09m)^2}\right]\]

I just needed to cancel my units out to make sure I'm doing the calculations correctly, because the answer is supposed to be in N/C
