Um elétron é lançado entre duas placas eletrizadas como mostra a figura. sejam v= 6x10^6 m/s, ângulo 45°, e= 2x10^3 n/c, d= 3 cm, l=12cm, m=10^-30 kg, e=1,6x10-19 c. despreze a ação gravitacional.
a) o eletron atingirá a placa negativa?
b) determinar a posicao em que o eletron atinge uma das placas.

Two large, flat, horizontally oriented plates are parallel to each other, a distance d apart. half way betwween the two plates the electric field has magnitude e. if the separation of the plates is reduced to d/2 what is the magnitude of the electric field half way between the plates?
