The electrical force between two charged objects is directly proportional to the product of the magnitudes of their charges and inversely proportional to the square of the distance between them. This relationship is described by Coulomb's Law, which states:
\[ F = k \frac{|q_1 q_2|}{r^2} \]
where \( F \) is the magnitude of the electrical force, \( k \) is Coulomb's constant, \( q_1 \) and \( q_2 \) are the charges of the objects, and \( r \) is the distance between the centers of the two charges.
Therefore, regarding how the electrical force relates to the charge of an object:
- It is directly proportional to the product of the charges of the two objects.
However, if you're referring to the relationship between the force and the charge of a single object (with respect to a constant charge), then:
- The electrical force exerted on that object is directly proportional to the charge of that object.
Hence, the correct option is: It is directly proportional to the charge.
