Examiner notes & key calculations

  • Unit Conversion Errors: Many candidates failed to convert prefix units correctly, notably millimeters to meters in electric field spacing, and milliseconds to seconds when determining capacitor time constants.
  • Neglecting Multi-State Calculations: In the nitrogen phase-change question, candidates frequently neglected the fact that energy transferred from the ice must account for *both* the latent heat of fusion and the latent heat of vaporization of water, resulting in incomplete energy equations.
  • Graph-Reading Inaccuracies: Calculating experimental gradients requires choosing a large triangle (spanning at least half the plotted data range). Examiners noted several instances of tiny triangles, leading to significant rounding errors.
  • Misunderstanding Resultant Forces: A common conceptual pitfall was treating centripetal force as a separate force on the Venus space probe rather than the resultant force of gravity and upthrust.
