3D Electric Potential Distribution of Two Charges

①Demonstrates the 3D electric potential superposition surface of two point charges and its dynamic changes with parameters. ②Core math concepts: scalar field superposition, 3D function surfaces, and spatial coordinate modeling. ③Construction: Uses objects b, c, a from the summary, combined with sliders to adjust charge and position, generating a dynamic potential distribution plot. ④Suitable for high school physics or introductory college electromagnetism, ideal for intuitively understanding the principle of potential superposition and spatial field distribution.
