What to Focus On
- Charging by friction produces opposite charges on two materials.
- Like charges repel; unlike charges attract.
- Charge is conserved in an isolated system.
- Coulomb’s Law: F ∝ q₁q₂/r²
- k = 9 × 10⁹ Nm²/C² in vacuum
- Force is attractive for opposite charges, repulsive for like charges.
- Electric field E = F/q₀ (vector, unit: N/C)
- For a point charge: E = kq/r²
- Dipole field: axial E = 2kp/r³, equatorial E = kp/r³
Common Mistakes to Avoid
Electric field lines are real physical paths that charges follow.
Coulomb's law can be applied directly to any two charged objects, regardless of shape or size.
The electric field is zero wherever there is no charge.
Memory Tips
Two types of electric charges: positive and negative
Like charges repel, unlike charges attract
Conservation of charge
Quantisation of charge: Q = Ne
