Electric Charges & Electrostatics — Class 11 Physics Electric Charges Class 11 Physics  ·  Electrostatics Contents Introduction Conservation of Charge Quantization of Charge Methods of Charging Magnitude of One Coulomb Coulomb's Law Conceptual & Numerical Challenges Introduction Electrostatics , the earliest discovered branch of electricity, involves electric charges, the forces between them, and their behavior in materials. Just as masses are responsible for gravitational forces, electric charges are the fundamental property responsible for electrical forces. Matter is made up of atoms. Inside every atom, positive and negative charges are held together by the enormous attraction of the electrical force. Protons carry a positive charge, while electrons carry a negative charge. Protons are bound tig...
