Homework Statement
The questions are based off of the diagram I attached.
First, I had to find the strength of the electric field due to each charge at (0 cm, 8 cm).
Now I need to find the total electric field (both magnitude and direction) at (0 cm, 8 cm) and the total electric potential due to these three charges at the origin (0 cm, 0 cm) and (0 cm, 8 cm).
Homework Equations
E=[itex]\frac{KeQ}{r^2}[/itex]
V=[itex]\frac{KeQ}{r}[/itex]
Ue=qV_{TOT}
The Attempt at a Solution
I found the electric fields to be:
E_{1}= 2742295.52
E_{2}= 2742295.52
E_{3}= 8.33333.33
Now how do I go from here to the total electric field and then total electric potential?
