Experiment brief
ES-02 · K12–UniversityWhere is the potential zero, and why can the electric field there still be nonzero?
- superposition
- dipole symmetry
- E = −∇V

0 / 3 solved
- 1Predict
On the perpendicular bisector between the two charges, which way does the electric field point?
- 2Measure
Place the probe at the midpoint (0, 0) and read the field magnitude |E|.
±2% - 3Extend
Double the separation (charges at ∓0.28 m). What is |E| at the midpoint now? Predict, then check.
