Two particles, each with charge 52.0 nC, are located on the y axis at y = 25.0 cm and

y= - 25.0 cm.

(a) Find the vector electric field at a point on the x axis as a function of x.

(b) Find the field at x = 36.0 cm.

(c) At what location is the field 1.00i kN/C?

(d) At what location is the field 16.0i kN/C?
