Solution

Para resolver esta pregunta, sigamos los siguientes pasos:

  1. Identificar las cargas y su disposición:

    • Tenemos dos cargas opuestas de magnitud q q .
    • Están separadas por una distancia 2d 2d .
    • Queremos encontrar el potencial eléctrico en el punto medio entre estas dos cargas.
  2. Ubicación del punto medio:

    • El punto medio está a una distancia d d de cada una de las cargas.
  3. Fórmula del potencial eléctrico:

    • El potencial eléctrico V V debido a una carga puntual q q a una distancia r r es dado por: V=kqr V = \frac{kq}{r} donde k k es la constante de Coulomb.
  4. Calcular el potencial debido a cada carga en el punto medio:

    • Para la carga +q +q : V1=kqd V_1 = \frac{kq}{d}
    • Para la carga q -q : V2=kqd V_2 = \frac{-kq}{d}
  5. Sumar los potenciales:

    • El potencial total en el punto medio es la suma de los potenciales debidos a cada carga: Vtotal=V1+V2=kqd+kqd V_{\text{total}} = V_1 + V_2 = \frac{kq}{d} + \frac{-kq}{d}
  6. Simplificar la expresión:

    • Al sumar los potenciales, obtenemos: Vtotal=kqdkqd=0 V_{\text{total}} = \frac{kq}{d} - \frac{kq}{d} = 0

Por lo tanto, el potencial eléctrico en el punto medio entre las dos cargas opuestas es 0 0 .
