a) A velocity selector consists of electric and magnetic fields described by the expressions E = Ek and B = Bĵ, with B = 25.0 mT. Find the value of E (in kV/m) such that a 770 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 move undeflected in the negative x-direction? MeV
