An electric dipole is made of two charges of equal magnitudes and opposite signs. The positive charge, q = 1 μ?
C. is located at the point (x, y, z) = (0, 1 cm, 0) while the negative charge is located at the point (x, y, z) = (0, -1 cm, 0). How much work will be done by an electric field E = (3 × 106 N/C ) i hat to bring the dipole to its stable equilibrium position?

Distance between the two charges is d = 2 cm = 0.02m
Work needed = qEd = 1.e-6*3e6*0.02 = 0.06 J

I understand what you're asserting even with the undeniable fact that that is confusing explaining and fixing the question without diagram so i'm unlikely to be waiting to remedy it yet. in basic terms a splash, (with a bit of luck) is that one value is promptly below or on precise of your damaging value so the E promptly above or decrease than E4 we could call it's going to be placed into the Ey1 next the E this is horizontal with your E4 would be extra with the Ex1. ultimately Your E this is at a diagonal attitude to E4 because of fact it particularly is a sq. it's going to be at a 40 5 degree attitude save that throughout strategies and you should use pythogoras therorem to make your mind up the x and y vectors of this E and upload them to Ex1 and Ey1 as quickly as extra they are going to be your very final vectors or besides the fact that and you placed them mutually and make a triangle and with some trig back you will locate the importance of all 3 costs appearing upon E4. desire it is sensible and robust success
