can someone offer me an explanation for part b? I picked (3) for a certain reason, but I want to know why it would be 3 and not the others. (picture attached)

Best ResponseYou've already chosen the best response.1Qu: what would a positive charge "want" to do? for (1) and (2) it is obvious, move away from + toward . but for (3) .... and in each case ... the charge "wants" to lose energy. or you can see potentials as relative and, in the case of (3), add 400V to each side or go back to the fundamental definitions ... which will involve the dissipation of energy

Best ResponseYou've already chosen the best response.0an electrostatic field 'points' from high to low potential in a way consistent with Laplace's equation (which is a steadystate special case of Maxwell's equations), so in (b) we're looking for an arrangement where the potential on the left is higher than that on the right

Best ResponseYou've already chosen the best response.0So wait, so for part b. I know that the KE is arranged as alpha, proton, electron. But why would the electron be the other way around? electron, proton, alpha for the greatest to least velocity.
