    An electron falls through a distance of 2 cm ir a uniform electric field of magnitude 6.0 xx 10^4 NC^(-1) figure (a). The direction of the field is reversed keeping its magnitude unchanged and a proton falls through the same distance figure (b). Compute the time of fall ir each case. Contrast the situation with that oi 'free fall under gravity'. m_(e) = 9.1 xx 10^(-31)kg, m_(p) = 1.7 xx 10^(-27) kg and e = 1.6 xx 10^(-19) C

    An electron of mass m_(e ) initially at rest moves through a certain distance in a uniform electric field in time t_(1) . A proton of mass m_(p) also initially at rest takes time t_(2) to move through an equal distance in this uniform electric field.Neglecting the effect of gravity, the ratio of t_(2)//t_(1) is nearly equal to
