- Explain what is meant by an electric field.
- Recognise and use the expression for electric field strength E = F / Q
- Draw and interpret diagrams using lines of force to describe radial electric fields qualitatively.
- Use the expression F = k Q Q / r where k = 1 / 4
- Derive and use the expression E = k Q / r for the electric field due to a point charge.
