Study Notes
Coulomb's Law
- Describes the electrostatic force between two charges (q1 and q2).
- The force magnitude depends on the distance (r) between the charges.
- Coulomb's constant (k) is a key factor: k = 1/(4πε₀) = 8.99 x 10⁹ N·m²/C².
- Vacuum permittivity (ε₀) is approximately 8.85 x 10⁻¹² F/m.
Electric Field
- Defined by the equation E = k(q/r²).
- Electric field strength (E) increases with charge (q) and decreases with the square of the distance (r).
Field Lines
- Visual representation of electric fields.
- Proximity of field lines indicates strength: closer lines signify a stronger field, while farther lines indicate a weaker field.
