How an electron moves when it is released from rest to a positively charged hollow cylinder? The hollow cylinder is finite and insulating. The electron is constrained to move only in z direction (into the center of the hollow cylinder). My thinking is that there is no electric field inside the hollow cylinder. Therefore, the electron will not be affected by the electric field. So what causes it to move should be gravitational force and it should travel towards the earth? But an electron's mass is tiny so gravity can be ignored here? Also, the next task asks me to calculate the work done by the electric field on the electron to make it travel. I think I'm not on the right track now.
Any help would be much appreciated.
Thank you.
