Answer

Explanation:

Step1: Record la ley de Coulomb

La fuerza eléctrica entre dos cargas puntuales está dada por $F = k\frac{q_1q_2}{r^2}$, donde $k$ es una constante, $q_1$ y $q_2$ son las cargas y $r$ es la distancia entre ellas.

Step2: Analizar el cambio de distancia

Las bolas se acercan, lo que significa que $r$ disminuye. Las cargas $q_1$ y $q_2$ son constantes.

Step3: Determinar el cambio de la fuerza

Como $F = k\frac{q_1q_2}{r^2}$, cuando $r$ disminuye, el valor de $F$ aumenta.

Answer:

A. The electric force increases.
