# Electric fields between point charges

• AliTheAlienTV
In summary, there is a discussion about the convention of referencing the angle from the positive x-axis instead of the y-axis. It is pointed out that the solution should state "angle from the line AP" instead of "to the line AP".

Homework Statement
Question 2c: I've attempted the question, I've got the magnitude right but I got the angle wrong. I don't understand why the value of the components are swapped around.

I’m guessing it’s just convention to reference the angle from the positive x-axis instead of the y-axis.

To nitpick your solution should say “angle from the line AP” not “to the line AP”
