Point charge q₁ = - 5.00 nC is at the origin and point charge q₂ = + 3.00 nC is on the x-axis at x = 3.00 cm. Point P is on the y-axis at y = 4.00 cm. (a) Calculate the electric fields at point P due to the charges q₁ and q₂. Express your results in terms of unit vectors (see Example 21.6). (b) Use the results of part (a) to obtain the resultant field at P, expressed in unit vector form.
