hi
i am stuck on the question in the image i have attached, I am unsure of how to go about the question.
the principles i am trying to use:
conservation of energy for the electron
so ki+ui=kf+uf
where k is the kinetic energy and u is the potential energy of the electron,
The electron does positive work moving upwards against gravity.
The electron will loose potential energy in moving closer to the positive charged plate.
I am not sure how to work out the change in potential energy of the electron.
