Strength

• What happens to the force between two charges as they get closer together?

  The force becomes stronger
• What is the behavior of like charges when they are near each other?

  Like charges will repel each other
• What happens when opposite charges are brought close together?

  They experience an electrostatic attraction
• How does the distance between two charges affect the force between them?

  As the distance increases, the force becomes weaker
• What concept explains the change in force with distance from a charge?

  The idea of electric fields
• What is an electric field?

  A region where charges experience electrostatic forces
• How does the strength of an electric field change with distance from the charge?

  The electric field becomes weaker with distance
• How can you visually represent the strength of an electric field?

  By the density of field lines
• What do closely spaced field lines indicate about an electric field?

  They indicate a strong electric field
• What do widely spaced field lines indicate about an electric field?

  They indicate a weak electric field
• How do field lines behave around a positively charged sphere?

  They point away from the sphere
• What is the relationship between the size of a charge and the strength of its electric field?

  Larger charges generate stronger electric fields
• If one charged sphere has a charge of 1 kC and another has a charge of 10 kC, which has a stronger electric field?

  The sphere with a charge of 10 kC
• How can the strength of an electric field be visually represented?

  By the number of field lines drawn
• What factors determine the strength of an electric field?

  • Distance from the charge
  • Size of the charge
• What should you be able to explain regarding electric fields for your exams?

  • How the strength of an electric field changes with distance
  • How to interpret field lines to determine field strength
