"Symmetry" Consider the figure below. The blue balls are located at (-1,1,0) and (1,-1,0) each carry a charge, Q. The green balls are located at (1,1,0) and (-1,-1,0). They each carry a charge -Q. There are three points marked in red, O is the origin, P1 is (0,0,2) and P2 is (2,0,0). There are no charges at these points. I would like to rank the points O, P1, and P2 in order of decreasing electric field strength. The correct answer is: - P1>P2>O
- O>P1>P2
- P1>O>P2
- O>P2>P1
- O>P2=P1
- P2>P1=O
- P2>P1>O
- P1=P2>O
- The fields are all equal
- None of the above
Please explain your answer in words, not equations.
