This is not really a homework question, just a question I came up with. If the Earth is pulling, for example, a book with a force of 5 N, that means, due to Newton's 3rd law, that the book is also pulling the Earth with a force of 5 N.
Does this mean the total force between them is actually 10 N (since they are each pulling each other with a force of 5 N)? That would imply you would need over 10 N to pick up the book, but I know you only need anything over 5 N. So what am I missing here?
