(a) A velocity selector consists of electric and magnetic fields described by the expressions E = EK and B = B, with B = 25.0 mT. Find the value of E (in kV/m) such that a 780 eV electron moving in the negative x-direction is undeflected. 414.0 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? Mev 7.68 Need Help?
