Question: A point charge with Q1=2e-7 Coulombs is placed at the point y=-0.05 meters on the negative y-axis and another charge Q2 = 2e-7 Coulombs is placed at the point y=0.05 meters on the positive y-axis.
Question I: Find the electric field, magnitude and direction, at the point x=0.15 meters on the x-axis.
If possible just a brief explanation how you got the answer? Thanks.
