Which combination of charged objects will have the strongest electrostatic attraction force between them?

• Objects #1

• Objects #2

• Objects #3

• All will have equal electrostatic attraction force between them.

Opposite charges attract each other. Like charges repel each other.

What is the name of the natural law?

• Law of Charges

• Coulomb's Law

• Ohm's Law

• Law of Poles

The magnitude of the electrostatic attraction or electrostatic repulsion force between two charged objects is proportional to the product of the charges and inversely proportional to their distance squared?

What is the name of the natural law?

• Law of Charges

• Coulomb's Law

• Ohm's Law

• Law of Poles

The electrical current through a circuit is proportional to the voltage applied across the circuit and inversely proportional to the resistance on the circuit.
