# A +12 nC charge is located at the origin

A +12 nC charge is located at the origin.

What are the electric fields at the positions (x,y) = (5.0 cm, 0 cm), (-5.0 cm, 5.0 cm), (-5.0 cm, -5.0 cm)? Write each electric field vector in component form.

I got the answer for the first one, but I can't figure out how to get the answers for the second and third ones. The answers are suppose to be (-1.53*10^4 i + 1.53*10^4 j) N/C and (-1.53*10^4 i - 1.53*10^4 j) N/C, respectively.

Thank you!
