Study Notes

Like Charges Repel

  • Like charges (charges of the same sign, either both positive or both negative) repel each other.
  • This means that two positive charges or two negative charges will exert a repulsive force on each other.

Characteristics of Repulsion:

  • The repulsive force between like charges is proportional to the product of the magnitudes of the charges.
  • The repulsive force between like charges is inversely proportional to the square of the distance between the charges.
  • Like charges repel each other with a force that is always directed along the line joining the charges.

Examples:

  • Two positive charges, +q and +Q, will repel each other.
  • Two negative charges, -q and -Q, will repel each other.
  • The repulsive force between like charges can cause them to move away from each other.

Importance of Repulsion:

  • The repulsion between like charges plays a crucial role in many natural phenomena, such as:
    • The structure of atoms and molecules
    • The behavior of electric currents
    • The formation of electric fields
