Hello I'm new here and I don't know if this is the right place but I just got my "electrical engineering" book in the mail and I started to flip through it. It look really intresting and all so I decided to read some of the examples it had I figured most of them out but got to this question and I just don't get it! I may be a complete idiot when you see the question but I just need some explanations. the question is: Find the force acting vertically downwards on a mass of 200 g attached to a wire. so how do you figure this out?
