Question

an electron and a proton (electron with charge -e, and proton with charge +e) are accelerated through a potential of 100 volts. after this acceleration we can say that:

a) the mass of the electron and the mass of the proton must be the same

b) the speed of the electron and the proton are the same, and their kinetic energies are the same

c) the momentum of the electron and the proton are the same

e) the spin of the electron is opposite to that of the proton

Answer 1

I Energy (E) = Ber pofential Every will he same = eu fom Energy consumaton Kineker Eursy = polental Engly mv2 = ev. nof renany pary that maus to re some а), we Cam ke my - и Кауна ал же, x 6 necessary same with speed as mais, nelesare momeu -mv speech will be same. o momentura (0) = mv so if wrong - sign of change is apporte so Cugy is same & mrzis same noh my Spin will be apposite
