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.
