Hi, I have another Electromagnetism question! Please see attached.
I just need a clue to where to start. Since its asking for speed I'm assuming I'm going to need to use F=qvB at some stage...? But it also gives me a potential difference which makes me think I need to use ∆U=∆Vq? Am I at least on the right track or is there something I'm missing?
Thank you!

Sorry I somehow missed this earlier!
You may have resolved this by now, but my approach would be to use the change in energy to get the kinetic energy and thus speed :)

Hi everyone! If someone could help me out, I would really appreciate it. I've attached a photo of some diagrams regarding F=qvBsinθ. Can someone just confirm for me what the answers are for each of these? The Textbook doesn't have any answers and I've been finding these pretty difficult so I just want to confirm that I've been getting it right. It uses Fleming's Left-Hand Rule.
Thank you! Hope everyone is keeping well.
