Question

which statements describe the factors affecting the strength of an electrical force? check all that apply.
the weaker the charge on two objects, the stronger the electrical force between them.
the stronger the charge on two objects, the stronger the electrical force between them.
the charge of the two objects does not affect the strength of the electrical force between them.
the closer together two objects are, the stronger the electrical force between them.
the farther apart two objects are, the stronger the electrical force between them.
the distance between two objects does not affect the strength of the electrical force between them.

Explanation:

According to Coulomb's law \(F = k\frac{q_1q_2}{r^{2}}\) (where \(F\) is the electrical force, \(k\) is a constant, \(q_1\) and \(q_2\) are the charges of two objects, and \(r\) is the distance between them). When \(q_1\) and \(q_2\) increase (stronger charge), \(F\) increases. When \(r\) decreases (closer together), \(F\) increases.

Answer:

• The stronger the charge on two objects, the stronger the electrical force between them.
• The closer together two objects are, the stronger the electrical force between them.
