It's M1 and its questions 5 part 1 and c

Thanks in advance... BTW not entering my working as it is shocking as I genuinely had very litttle idea as to what the question was asking...

It will be best that you post it on the forum.

I have never done a question of that type, so i can't help you on it.

Which part are you stuck on?

Hi could I have some help on Q7 on this paper pls??
I am struggling with the wording of it..

Um, I kind of understand the top 9N bok it was the bottome 3 N force as on the markscheme it said that the coewfficient of frcition for it will not change and it also mentioned something about traction force, which I have never heard off :/

I haven't given much attention to your working, though i will try to explain it.

Now the lower particle(3N) will exert a vertical normal reaction on the upper particle(9N).

The diagram will look like this:




Now resolve the forces,




NB: I forgot to show friction on the diagram.

Does it makes sense?
