Electricity 23-24

What does the study of electrostatics involve?

• The study of electric currents and magnetic fields

• The study of electric charges at rest, the forces between them, and their behavior in materials

• The study of electrical appliances and their functionality

• The study of solar electricity and its applications

What is the fundamental rule at the base of all electrical phenomena according to the text?

• Like charges attract and opposite charges repel

• All charges attract

• All charges repel

What type of forces are described as being billions of times stronger than gravity and capable of balancing each other out with no noticeable effect on you?

• Magnetic forces

• Gravitational forces

• Electrical forces

• Nuclear forces

What is the result of the interaction between the electrical forces and the gravitational force on your body according to the text?

• The electrical forces completely negate the gravitational force.

• The gravitational force is stronger than the electrical forces.

• The electrical forces and gravitational force enhance each other.

• The electrical forces balance out, leaving the weaker force of gravity, which only attracts.
