Electric fields written questions
Practise H2 Physics electric fields, Coulomb forces, potentials, charge motion and capacitor energy, using marking guidance to review written reasoning.
Learning goals
- Apply Coulomb's law to the force between point charges.
- Define electric field strength and calculate resultant fields due to point charges.
- Define electric potential and calculate potential due to point charges.
- Relate electric potential, potential energy and work for systems of point charges.
- Use the negative potential gradient and relate equipotentials to field lines.
- Calculate field strength and force in uniform electric fields.
- Analyse charged-particle motion in uniform electric fields.
- Apply capacitance and capacitor-energy relationships.
