This is a discussion post. We were asked to watch a video called 5 fun physics phenomena posted on YouTube by "Veritasium" (number 3 is the main focus) https://youtu.be/1Xp_imnO6WE Questions; 1.) The common explanation is that since water is a polar molecule, the electric field from the charge on the cup will exert a greater force on one side of the water molecules than on the other side, attracting the stream of water. What explanation does the host (from the YouTube video) give that this effect is negligible? Does this sound reasonable and why or why not? (Uniform E-field means one that doesn't change position.) (The explanation the host gave was that "if you have a uniform electric field there's an equal force pulling the positive side towards it as there is pushing the negative side away from it. And so you can't actually do more than just turn the molecules. You would need a really strong gradient in your electric field to make this work at all and it basically won't happen from a cup".) (It will make more sense after watching the YouTube video) 2.) If the polar nature of water is not the main (direct) explanation, then what is? Make a detailed hypothesis as to the correct reason why the stream of water is deflected by an electric charge. 3.) another video: (https://youtu.be/jIMihpDmBpY watch from 3:48) What actual reason was given by the host? How is it similar to your explanation? I really need help please. Thank you! I apologize if it's a bit confusing
