SUMMARY
The discussion centers on calculating the change in electric potential energy when a +12.5 µC charge is moved in a uniform electric field of 6890 N/C. The correct formula used is U = qEd, where q is the charge, E is the electric field strength, and d is the distance moved. The initial calculation mistakenly used millimeters instead of centimeters for the distance, leading to an incorrect result. After correcting the distance to 5.87 cm, the accurate change in electric potential energy is determined to be 0.00050555 J or 0.50555 mJ.
