About OCR A Level Physics A Nuclear and Particle Physics

This topic covers nuclei and particles.

What you need to know

  • Nucleus Rutherford scattering and nuclear radius.
  • Particles Hadrons, leptons and quarks.
  • Radioactivity Decay law and half-life.
  • Energy Binding energy, fission and fusion.

Common mistakes in Nuclear and Particle Physics

  • Wrong quark charges.
  • Mixing count rate and activity.
  • Saying binding energy is released by splitting all nuclei.

Try three Nuclear and Particle Physics exam-style questions

1. State the charge of an up quark. (1 mark)

Show the mark scheme answer

+⅔e.

2. Explain what alpha scattering showed. (2 marks)

Show the mark scheme answer

Most alphas passed straight through, so atom is mostly empty (1); a few deflected strongly, so a small dense positive nucleus (1).

3. Give the half-life equation. (1 mark)

Show the mark scheme answer

t½ = ln 2/λ.
