Fuerza electrica $\vec{F} = K \cdot \frac{q \cdot q'}{r^2} \cdot \vec{u_r}$ $\vec{F} = q' \cdot \vec{E}$

Fórmulas esenciales del campo eléctrico

La fuerza eléctrica entre dos cargas se calcula con F=Kqqr2F = K \frac{q \cdot q'}{r^2}, donde K es la constante de Coulomb. También puedes usar F=qEF = q' \cdot \vec{E} cuando ya conoces el campo eléctrico.

El campo eléctrico se define como E=Kqr2\vec{E} = K \frac{q}{r^2}, y representa la fuerza que experimentaría una carga unitaria en ese punto. Recuerda que K=14πϵK = \frac{1}{4 \pi \epsilon}, donde ϵ\epsilon es la permitividad del medio.

Para el potencial eléctrico, usa V=KqrV = K \frac{q}{r} y la energía potencial será Ep=qVE_p = q \cdot V. El trabajo realizado por el campo se calcula con W=q(VBVA)W = -q'(V_B - V_A).

Truco clave: Si solo actúa el campo eléctrico, la energía se conserva: qδV=12m(vf2vo2)-q \delta V = \frac{1}{2} m (v_f^2 - v_o^2)

El flujo eléctrico se define como Φ=ES=EScosα\Phi = \vec{E} \cdot \vec{S} = E \cdot S \cdot \cos \alpha. Según el teorema de Gauss, el flujo a través de una superficie cerrada es Φc=qϵ\Phi_c = \frac{q}{\epsilon}, una herramienta súper útil para calcular campos en geometrías simétricas.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
