Electromagnetic interactions involve particles that have a property that is as fundamental as mass. What is that property called as?

• Electric Field

• Electric Force

• Electric Charge

• Electricity

The ancient Greeks discovered as early as 600 B.C. that after they rubbed amber with wool, the amber could attract other objects? Why does amber behave this way?

• It is being possessed.

• It is its nature to behave that way

• It became a negatively charged object.

• It became a positively charged object.

What is the primary role of electron transfer in electrostatic charging by rubbing?

• Proton movement

• Electron movement

• Neutron movement

• Nucleus movement

Which statement best describes the process of electron transfer in electrostatic charging?

• Electrons remain stationary in both objects

• Electrons are created during the process of rubbing

• Electrons are destroyed during the process of rubbing

• Electrons move from one object to another through friction

What is a crucial step in demonstrating electrostatic charging by induction?

• Rubbing two objects together

• Heating an object until it becomes charged

• Touching a negatively charged object to a neutral object

• Bringing a charged object close to a neutral object without touching

When a positively charged object is brought near a conducting sphere, what happens to the charges in the sphere?

• Positive charges are neutralized by the object's charge

• Positive charges remain where they are, and negative charges move away

• Positive charges move away from the object, and negative charges move closer

• Positive charges move to the side closer to the object, and negative charges move away

How can you verify that an object has been charged by induction?

• Seeing the object repel positive charges

• Observing a spark when touching the object

• Placing the object in water and observing bubbles

• Using an electroscope to detect the charge without physically touching the object

What happens if a negatively charged object is brought near a neutral conducting sphere?

• Nothing happens to the sphere

• The sphere becomes positively charged

• The sphere becomes negatively charged

• Charges in the sphere rearrange, with positive charges near the object and negative charges far

The net electric force between two charges is attractive when:

• The charges are neutral

• The charges are of the same sign

• The charges are of opposite signs

• The charges have different magnitudes

What is the relationship between electric force and electric field?

• The electric field on a charged body is exerted by the electric force created by other charged bodies.

• The electric force on a charged body is exerted by the electric field created by other charged bodies.

• Both are correct
