Question

compara tus observaciones y determina qué factores parecen afectar la intensidad de la fuerza eléctrica. selecciona todas las respuestas correctas.
a. la distancia entre los objetos
b. la magnitud de las cargas
c. la masa de los objetos
d. el signo de las cargas

Explanation:

Step1: Recall Coulomb's Law

Coulomb's Law is \( F = k\frac{q_1q_2}{r^2} \), where \( F \) is the electric force, \( k \) is a constant, \( q_1 \) and \( q_2 \) are the magnitudes of the charges, and \( r \) is the distance between the charges.

Step2: Analyze each option

• Option A: From \( F = k\frac{q_1q_2}{r^2} \), the distance \( r \) between the objects affects the force. As \( r \) increases, \( F \) decreases.
• Option B: The magnitudes \( q_1 \) and \( q_2 \) of the charges are in the numerator of Coulomb's formula. Larger charges mean a larger force.
• Option C: Mass is not part of Coulomb's Law (\( F = k\frac{q_1q_2}{r^2} \)), so it does not affect the electric force.
• Option D: The sign of the charges only indicates if the force is attractive (opposite signs) or repulsive (same signs), but it does not affect the magnitude (intensity) of the force. The formula \( F = k\frac{q_1q_2}{r^2} \) uses the magnitudes of the charges.

Answer:

A. la distancia entre los objetos, B. la magnitud de las cargas
