If a magnetic field and an electric field are pointing in opposite directions, how can the net force (electric plus magnetic) on an electron be equal to zero?
Answer: It is not possible for the net force to be zero
My question is why is this the case? I am having troubling conceptualizing it.

What point on an X axis is the magnetic field zero if the currents are in opposite directions?
A long wire carrying a 5.5 A current perpendicular to the xy-plane intersects the x-axis at x=- 2.0 cm . A second, parallel wire carrying a 2.5 A current intersectsthe x-axis at x= 2.0 cm.At what point on the x-axis is the magnetic field zero if the two currents are in opposite directions?

Stop and hypothesize what the field diagram would look like for two opposite charges. Are there going to be areas where the value is 0? Where would they be if so? Why not, if you think this is the case? I BELIEVE THE BELOW IDEA I HAVE IS INCORRECT With two opposite charges there would be no value where the electric field is zero unless there is a distance equal to 0 between them, but that can’t be so based...
