1. The problem statement, all variables and given/known data An electron travels with speed 4.91×107 m/s between the two parallel charged plates. The plates are separated by s=1.47 cm and are charged by a 203 V battery. What magnetic field strength will allow the electron to pass between the plates without being deflected? ----------+------- < postive plate >>>>O < electron ----------(-)------- < negative plate 2. Relevant equations I thought that Fnet=Fe+Fm Fe= electric force Fm=magnetic force 3. The attempt at a solution Set it equal to zero o=Fe+Fm Fe=Fm (Kq1)/(r^2)=qVB solve for B....that didn't work what am I doing wrong?
