**1. Homework Statement**

A charge [tex]q_1= 7.0\mu C [/tex] is located at the origin, and a second charge [tex]q_2= -5.0 \mu C [/tex]is located on the x-axis, 0.30m from the origin. Find the electric field (maginitude and direction) at the point P, which has the coordinates (0,0.40)m.

**2. Homework Equations**

[tex]E = k_e \sum \frac{q} {r_i^2} \hat{r} [/tex]

**3. The Attempt at a Solution**

well,

[tex]q_1= 7.0 \mu C [/tex]

[tex]q_2= -5.0 \mu C [/tex]

r= 0.30m

y= 0.40m

how would I find the field if I'm given the coordinates of 0, and 0.40 which would mean that If I'm reading that right. then it would mean that it's 0.40m above the charges in the y direction?

Not sure if this picture is correct but I tried to draw the layout of the problem.
