Question: point charge q1 500 nc is at the origin...
Question details
Point charge q1 = 5.00 nC is at the origin and point charge q2 = +3.00nC is on the x axis at x = 3.00cm. Point P is on the yaxis at y = 4.00cm.
Part A
Calculate the electric fields E⃗ 1 and E⃗ 2 at point P due to the charges q1 and q2. Express your results in terms of unit vectors (see example 21.6 in the textbook).
Express your answer in terms of the unit vectors i^, j^. Enter your answers separated by a comma.

Part B
Use the results of part (a) to obtain the resultant field at P, expressed in unit vector form.
