Corrections:
Ignore some of my statements about venn diagrams for q3. Clearly I misstated independent and mutually exclusive. Apologies.
Mechanics question 2 (b). My final conclusion was incorrect. µ is actually inversely proportional to the distance of the centre of mass to B. so as the centre of mass gets closer to B, µ increases. My reasoning was correct, I simply misstated the final conclusion.
