Physics p41???

Did anyone do this paper.......i have a couple of questions about it?
the momentum ratio was the smaller radius over the bigger one or the opposite.
i think that the electric potential question was tough.
IMO the exam was easy despite some questions but the applications part was harder than usual/
thanx

yes it was smaller by larger

da direction was 4rm bottom to top..

and applications part was hard ur ryte.

electric potential.....welll...i dont get y was it 4 4marks 4 simple algebra..
tht quesiton made me waste 10 min!!!!

What did u get for the mass of the shm particle? i got 50 grams.
when they ask u in the first question why newtons law of gravitation is valid on the sun and
the planets? i wrote because they are isolated masses what did u right.
in the transformers question, they ask u to use faradays law to explain why the emf in the
supply and the load are not in phase, what did u say?
thanx
