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 |
