Given symmetrically placed rectangular insulators with uniformly charged distributions of equal magnitude as shown in the figures be low, find the net electric field at the origin.
In the figure above, at the origin, the net field Enet is
1. aligned with the positive y-axis.
[STRIKE]2. non-zero and is not aligned with either the x- or y-axis.[/STRIKE]
[STRIKE]3. zero and the direction is undefined.[/STRIKE]
4. aligned with the positive x-axis.
5. aligned with the negative x-axis.
6. aligned with the negative y-axis.
2 and 3 were wrong.
The Attempt at a Solution
I think they are asking for the direction of the electric field. Actually, I have no idea what I am supposed to solve for. I know I have to find Enet but how? Thanks in advance!
