I have this question that I have been pondering about for over an hour now :
What is the final speed of an electron accelerated through a potential difference of 200V if it has an initial speed of 2.0x10-6C and mass of electron +9.11x10-31.
Now I read the forum rules and I knowI have to help myself if I want others to help me...but I am totally stuck: because the only method I can think of is obviously wrong i.e. finging the weight of electron and that being the electrical force. Also even if I got that and could get the electric field strenght and distance between the pd...what next?
Thanks
