SUMMARY
The discussion focuses on calculating the electric field from potential energy in a uniform electric field scenario. The potential at points (0,0) and (.5,0) is 20V higher than at (0,.5), leading to the conclusion that the electric field has a magnitude of 40 N/C in the positive j-direction. The reasoning is based on the relationship between electric potential difference and electric field, confirming that the field points in the direction of decreasing potential. The correct answer is option b) 40 N/C j.
