Avelocity selector has a magnetic field of magnitude 0.26 t perpendicular to an electric field of magnitude 0.46 mv/m. what must the speed of a particle be for it to pass through undeflected?

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

a is the best answer your welcome
