Homework Statement
A -12nC charge is located at (x,y) = (1.0cm, 0cm). What are the electric fields at the positions (x,y) = (5.0cm, 0cm), (-5.0cm, 0cm), and (0cm, 5.0cm)? Write each electric field vector in component form.
Homework Equations
E=k(q/r2)
The Attempt at a Solution
I was able to find the magnitude of the electric fields at the first two positions, but I am not sure how to find the last one. Also, how would you define the signs in this case for the first two electric fields? The answer for the first two were: -6.8x104 i N/C, 3.0x104 i N/C.
