An electron , with charge of -1.60 xx 10^(19) C , accelerates from rest through a potential difference V. A proton , with a charge of + 1.60 xx 10^(-19) C , accelerates from rest through a potential difference -V . Is the final speed of the electron (a) more than , (b) less than , or (c ) same as the final speed of the proton ?
