SUMMARY
The discussion centers on calculating the electric potential at a corner of a rectangle where three corners have 2.0 nC charges. The key equations referenced are U=(kQq)/r for electric potential energy and V=(kq)/r for electric potential. The conclusion is that while there is no electric potential energy at the fourth corner due to the absence of a charge, the voltage can still be calculated by summing the contributions from the charges at the other corners. The correct approach involves calculating the potential from each charge and summing them to find the total voltage at that point.
