The electrical force between two charged objects depends on: – The amount of charge on each of the two objects. – The amount of combined charge of both objects. – Which object has the greatest charge. – The mass of the objects.
The Correct Answer and Explanation is:
Correct Answer:
✔️ The amount of charge on each of the two objects.
Explanation:
The electrical force between two charged objects is governed by Coulomb’s Law, a fundamental principle in electrostatics. This law describes the interaction between electrically charged particles. According to Coulomb’s Law, the magnitude of the electrical force (F) between two point charges is directly proportional to the product of the magnitudes of their charges (q₁ and q₂) and inversely proportional to the square of the distance (r) between them:F=k⋅∣q1⋅q2∣r2F = k \cdot \frac{|q_1 \cdot q_2|}{r^2}F=k⋅r2∣q1⋅q2∣
Where:
- FFF is the magnitude of the electrostatic force,
- kkk is Coulomb’s constant (8.99×109 N\cdotpm2/C2)(8.99 \times 10^9 \, \text{N·m}^2/\text{C}^2)(8.99×109N\cdotpm2/C2),
- q1q_1q1 and q2q_2q2 are the amounts of charge on each object,
- rrr is the distance between the centers of the two charges.
The correct statement is that the force depends on the amount of charge on each of the two objects. This means both charges individually contribute to the magnitude of the force. If either charge increases, the electrical force increases. The force does not depend on the combined total charge, nor does it rely on which object has the greater charge. Additionally, the mass of the objects plays no role in determining the electrical force; mass affects gravitational force but not electrostatic force.
To illustrate: if two objects carry charges of +3 C and +2 C, their interaction is the same regardless of which object has which charge. What matters is their individual values and their separation distance. Hence, understanding Coulomb’s Law is essential to accurately predict how charged objects will interact
