# Problem: Three positive point charges (Figure 1) are spaced equally along the y axis (), = 5.00 at , = 5.00 at , and = 5.00at . Find the x and y components of the total electric field and at point, which is located on the x-axis at x = 6.00

In this problem, we'll use the equation of the electric field at a point due to charge, q:

$\overline{){\mathbf{E}}{\mathbf{=}}\frac{\mathbf{k}\mathbf{q}}{{\mathbf{r}}^{\mathbf{2}}}}$, where r is the distance between the charge and the point. k is Coulomb constant.

Let's review what we have:

q1 = 5.00 nC at y = 8 cm

q2 = 5.00 nC at y = 0 cm

q3 = 5.00 nC at y = - 8 cm

All the charges are positive.

This means that the electric field from each charge would be directed away from the charges.
