Question 4 • EA ACADEMY PHYSICAL SCIENCE SPRING

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.

Answer
A
The weaker the charge on two objects, the stronger the electrical force between them.
B
The stronger the charge on two objects, the stronger the electrical force between them.
C
The charge of the two objects does not affect the strength of the electrical force between them.
D
The closer together two objects are, the stronger the electrical force between them.
E
The farther apart two objects are, the stronger the electrical force between them.
F
The distance between two objects does not affect the strength of the electrical force between them.

Explanation

Electrical force gets stronger as the magnitude of the charges increases, and weaker as the distance between the objects increases (Coulomb’s law). So stronger charges produce a stronger force, and objects closer together experience a stronger force. The correct statements are “The stronger the charge on two objects, the stronger the electrical force between them” and “The closer together two objects are, the stronger the electrical force between them.”
