A positively charged rod of length 6m ranging from (0,0) to (6,0) has a charge density of 1 X 10^(-5) C/m. What is the magnitude and angle of the electric field at point (4,4)?
Wouldn't the electric field point toward the 2nd quadrant, making Enet= -Ex i + Ey j??
For Ex I got 10019.2 N/C (-i)
and for Ey I got 18721.1 N/C j
So wouldn't the magnitude be 2.1 X 10^4 N/C and the angle 118 degrees from the x-axis?
I am having trouble deciding the angle.
Since to the right is a shorter distance to the point than to the left, would the angle be in the first quadrant at 28 degrees?
Any help would be appreciated.
Thank you.
