Solve the all parts of given question:
Question: Two equal positive charges of magnitude q1 = q2 = 1.5 nC are on the y axis at y1 = +3 cm and y2 = -3 cm.
Part A: What is the magnitude and direction of the electric field on the x axis at x = 5 cm?
-------------- N/C + ------------------N/C
Part B: What is the force exerted on a third charge q0 = 3 nC when it is placed on the xaxis at x = 5 cm?
--------------------- N + ------------------ N
I need expert help to solve the above question.
