1. The problem statement, all variables and given/known data Attached picture with the given variables and questions stated. 2. Relevant equations E = kq / (r^2) 3. The attempt at a solution I've taken found the linear electric field magnitudes in relationship to the point q1 = 3.37e-9 q2 = 6.74e-9 q3 = 3.92e-9 r1 = .647m r2 = 1.941m E1 = (k*(q1))/(r1) = 72.3540189055 E2 = (k*(q2))/(r2) = 16.0789708679 I am having difficulty figuring out how to calculate the third vector into the total, any thoughts?
