Hello everyone, I'm just starting this problem and i'm already confused. I'm suppose to calculat the electric feild at the point P(x =3, y = 3) due to two charges, q1 = 4.0x10^-6C at the origin, and q2 = -3.0x10^-6C at x = 3.0m.(adsbygoogle = window.adsbygoogle || []).push({});

I'll try and draw the diagram.

....................................^ E1

.................................../

................................../

................................./

...............................(P)

................................|

................................|

................................v E2

(q1).........................(q2)

How did they know E2 will be point downard and E1 would be diagnoal like that? Thanks
