I was going to help, but the fact that you added an exclamation mark deterred me. I'm doing you a favour not the other way around.

E = kq/r^2
Field due to -9.0 micro C
Plug -9.0*10^-6 for q and 0.02 m for r (halfway)
Field due to 5 micro C
Plug 5.0*10^-6 for q and 0.02 m for r (halfway)
Add them to get the net field
