PARTICLE PHYSICS | 9702 P21 SOLVED | AS-Level Physics MAY/JUNE 2025 | Detailed EXPLANATION

In this video, we solve Cambridge AS-Level Physics 9702 Paper 21 (MAY/JUNE 2025) step by step, focusing on easy marks, common traps, and examiner expectations. QUESTION 7 (a) Nitrogen-12 (12 7N) is an unstable isotope of nitrogen that decays by the emission of radiation to carbon-12 (12 6C). Complete the full nuclear equation for the decay, including all the particles involved. 12 7N [3] (b) Hydrogen-1 (1 1H) is an isotope of hydrogen. An atom of hydrogen-1 comprises a proton with an orbiting electron. An antiparticle equivalent of hydrogen-1 comprises an antiproton with an orbiting positron. The antiquarks in the antiproton are the antiparticles of the quarks in a proton. (i) (ii) (iii) State the charge on the positron in terms of the elementary charge e. charge = ......................................... e [1] State the group (class) of fundamental particle to which the positron belongs.......................................................................................... [1] In Table 7.1, state the flavour and charge of the three antiquarks that comprise the antiproton.
