A point charge q1 -4 nC is at the point x = 0.600 m, y = 0.800 m, and a second point charge q2 +6 nC is at the point x = 0.600 m, y = 0. I need to calculate the magnitude of the net electric field at the origin due to these two point charges. | |................................. q1 (0.6, 0.8) | | | | | Origin--------------------q2 (0.6, 0) To solve this problem I was thinking of taking the distances of q1 and q2 from the origin and using that as the radius, I can plug into E = 1/(4piEo) * q1/r^2 r = 1 q1= -4nC and E = 1/(4piEo) * q2/r^2 r = 0.6 q2= +6nC and add them together to find the electric field at the origin. however when I did that, the answer turned out to be incorrect. What am I'm doing wrong? Thakn you for your help.
