A spherical surface completely surrounds a collection of charges. Find the electric flux (with its sign) through the surface if the collection consists of (a) a single +5.5 x 10-6 C charge, (b) a single -4.8 x 10-6 C charge, and (c) both of the charges in (a) and (b).(adsbygoogle = window.adsbygoogle || []).push({});

Ok, so this is what I've been able to figure out:

Ea=kq1/r^2=49445/r^2

Eb=kq2/r^2=-43152/r^2

and for part c: Ea + Eb = 6293/r^2

I'm just so confused as to how to get rid of the r^2.. Have I used the wrong equation entirely? Thanks so much to anyone who can help!
