Electric Charge and Electric Force

This study guide covers fundamental concepts of electric charge, including charge as a scalar quantity, Coulomb's Law, and the direction of electrostatic force. It compares electrostatic and gravitational forces, highlighting their relative magnitudes and dominance at different scales. Finally, it explores electric permittivity, explaining polarization, permittivity of free space, and permittivity in conductors and insulators. The guide emphasizes Coulomb's Law, the comparison of electrostatic and gravitational forces, and electric permittivity as high-priority topics for the exam.
