Interactive electrostatics tool for university-level Physics II
Place point charges, visualize the electric field in real SI units, and observe test-particle dynamics in real time.
No installation. No build step. Open and use.
All shortcuts work regardless of keyboard language (Hebrew, English, etc.)
All computation in strict MKS / SI. UI convenience scales (μC, nC, μg, cm) are converted at the boundary.
Field computation — Coulomb superposition: $$\vec{E}(P) = \sum_i \frac{k \cdot Q_i}{r_i^2} \hat{r}_i$$
*Q enters with its sign — no manual flip on r̂. Singularity clamp: r_min = 2 cm.*
