    Book Error Tube
AI Thread Summary
The discussion revolves around a perceived error in the 9th edition of the Serway book regarding the direction of the force acting on an electron in a cathode ray tube. The original poster believed the force should go upward based on the right-hand rules provided in the book, which led to confusion. However, they later clarified that they found their mistake and apologized for the initial post. The conversation highlights the importance of understanding the application of right-hand rules in magnetism. Overall, the thread emphasizes the learning process in physics and the value of peer support in resolving misunderstandings.

Hello. I was studying magnetism with the 9th edition of the Serway book and I think that I've found a mistake. In the cathode ray tube example (one of the uploaded pictures) it is said that the force acting on a electron goes downward, but using both right hand rules that they provide in the book - all I understand is that it goes upward. The right hand rules are in the uploaded pictures too. Can anyone help me with this?
