1 answer

The factors that affect the electrical force between two objects are:

Charge and distance between them.

According to Coulomb's Law, the electrical force \( F \) between two charged objects is directly proportional to the product of the magnitudes of their charges \( q_1 \) and \( q_2 \) and inversely proportional to the square of the distance \( r \) between them:

\[ F = k \frac{|q_1 q_2|}{r^2} \]

where \( k \) is Coulomb's constant. Thus, the key factors influencing the electrical force are the amount of charge on each object and the distance separating them.
