1. The problem statement, all variables and given/known data "A point charge of 3*10^-6 C is at the origin and another point charge of -4*10^06 C is at point 0.1m away along the x axis. What is the magnitude and direction of the electric field at point 0.15m from the origin along the posting y-axis? 2. Relevant equations E= Q/(4PIε°*r^2) ε°=8.85*10^-12 3. The attempt at a solution Electric Field from the first charge to the point on the Y axis: E1 = (3*10^-6)/(4PIε°*0.15^2) Electric Field from the Second charge to the point on the Y axis: E2 = (-4*10^-6)/(4PIε°*0.18^2) Magnitude Of Electric Field = E1+E2=88808N/C Direction is 158 Degrees from the X(got this from the vectors) This is my answer, my physics is really rusty and I have a gut feeling I've gone completely wrong. A checking and assistance would be appreciated. Thanks.
