• An electric field is defined as a region of space in which a?charged?particle experiences a?force
  • Hence, electric fields are a type of?force field
• The charged particle could be stationary or moving, and will experience an electric force in that field

• All charged particles create their own electric fields
  • These fields exert an electrostatic force,?FE?on other charged particles

The electrostatic force between two charges

• Like charges (positive and positive, or negative and negative)?repel?each other
  • This means the force on each charge are away from the other charge
• Opposite charged (positive and negative)?attract?each other
  • This means the force on each charge is?towards the other charge
• The size of the force changes with distance

A repulsive force decreases with distance
