(a) a velocity selector consists of electric and magnetic fields described by the expressions e = e and b = b ĵ, with b = 10.0 mt. find the value of e (in kv/m) such that a 740 ev electron moving in the negative x-direction is undeflected. kv/m (b) what if? for the value of e found in part (a), what would the kinetic energy of a proton have to be (in mev) for it to move undeflected in the negative x-direction?
