Hi all I'm just doing some practice papers and i've come unstuck on this question:
I can see why the N1 and N2 have a 1/2mg component, but I really don't get where the other parts come from. I've tried looking through my notes and Serway and Jewett but still can't figure it out. I've copy and pasted the answers underneath so people know what i'm on about
Are you going to achieve yours?
