[QUOTE="jackiepollock, post: 6523732, member: 688624"] Hello! I'm reading this part of the A-level physics book and finding a few places that I couldn't wrap my head around. They are underlined. 1) When saying oxygen, is it saying that oxygen is the most abundant element in the shoe atoms? 2)I am not too sure why the force per atom is shared between four electrons when there are eight in each oxygen atom. Despite the explanation it has given, I don't finding making sense and couldn't picture it. 3)When I follow the calculations, I see that the electric force is basically derived from the weight of the man, is it because the weight has caused a normal force, which is assumed to be the electric force? Thank you for the help![ATTACH type="full"]287042[/ATTACH][ATTACH type="full"]287043[/ATTACH] [/QUOTE]
