Hello,
I understand how to get the magnitude for the electric field in this problem. My only issue is that I cannot figure out why the i coordinate is sin while the j coordinate is cos. I had the problem entirely right except I had cos in the i spot and sin in the j spot. I'm sure this is a very easy explanation, I just have been staring at it for a while and can't understand the logic behind it.
Thank you.
