How does the magnitude of the electrical charge on objects affect the electric force between them?
A As the charge increases, the force decreases in strength.
As the charge increases, the force decreases in strength.
B As the charge increases, the force becomes more attractive.
As the charge increases, the force becomes more attractive.
C As the charge increases, the force increases in strength.
As the charge increases, the force increases in strength.
D As the charge increases, the force becomes more negative.
C As the charge increases, the force increases in strength.
C As the charge increases, the force increases in strength.
The correct answer is C: As the charge increases, the force increases in strength.
To understand why, we need to consider the basic principle of electromagnetism known as Coulomb's Law, which describes the relationship between the electrical charges on two objects and the electric force between them.
Coulomb's Law states that the magnitude of the electric force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. Mathematically, it can be expressed as:
F = k * (|q1| * |q2|) / r^2
Where:
- F represents the magnitude of the electric force,
- k is Coulomb's constant,
- q1 and q2 are the charges of the two objects, and
- r is the distance between them.
From this equation, we can observe that as the charges on the objects increase, the force between them also increases in strength. This is because the force is directly proportional to the product of the charges.
It's important to note that the force can be attractive or repulsive depending on the types of charges involved. Like charges (positive-positive or negative-negative) repel each other, while opposite charges (positive-negative or negative-positive) attract each other. However, the strength of the force increases as the magnitude of the charges increases, regardless of whether the force is attractive or repulsive.
