Thank you very much for your help--I'm having trouble with this problem: what do i do?

There are three point charges along the x axis:

-4nC(0.5m left of y axis)

5nC(at origin)

3nC(0.8 right of y axis)

I have to say what the electric field is at the point (2,0) and at the point (0,2).

How do i involve the different q values?

how do i solve for the electric field?

thank you for your help
