Electrostatic attraction

The video explains how similar charges repel each other according to Coulomb's Law. It details how the force of attraction or repulsion is proportional to the charge strength and inversely proportional to the square of the distance between them.

What is the primary interaction between similar charges?

• They merge together.

• They repel each other.

• They have no interaction.

• They attract each other.

According to Coulomb's Law, what happens to the force between two charges as the distance between them increases?

• The force decreases.

• The force increases.

• The force remains constant.

• The force becomes zero.

Which of the following is directly proportional to the force between two charges?

• The distance between the charges.

• The sum of the charges.

• The strength of the charges.

• The square of the distance between the charges.

What is the relationship between the force of attraction or repulsion and the distance between two charges?

• Directly proportional to the square of the distance.

• Directly proportional to the distance.

• Inversely proportional to the distance.

• Inversely proportional to the square of the distance.

Which factor does NOT affect the strength of the force between two charges?

• The strength of the charges.

• The color of the charges.

• The distance between the charges.

• The medium between the charges.
