(Electric force and field). Two charges, Q1 and Q2 of equal magnitude are placed at positions (0, −d/2, 0) and (0, +d/2, 0) respectively. Calculate the electric field at position (0, 0, z) when: a) Both charges are positive, and b) Q1 is positive, and Q2 is negative. What does the electric field become for the case z≫d for both cases a) and b) above?
