Key Topics

  • Coulomb's Law: F = k * (|q1 * q2| / r^2)

    • Measures the electrostatic force between charges.

    • k = 8.988 x 10^9 N.m²/C² (

  • Electric Charge:

    • Types: positive and negative. Positive charges repel other positive charges and attract negative charges.

    • Charge conservation principles and property of charge quantization (e = elementary charge).

Problems to Solve

  1. Coulomb's Law application: Determine the forces between charged objects.

  2. Charge distribution problems: Analyze how charges distribute over conductors.

  3. Electric field calculations: Work with electric fields generated by different charge configurations.

Important Formulas

  • Coulomb’s Law: F = k * (q1 * q2) / r²

  • Electric Field (E): E = F/q

  • Electric Potential (V): V = U/q

    • U: potential energy

  • Work done by electric field: W = qEd

  • Gauss's Law: Φ = (q_enc / ε₀)
