# Problem: Consider an experimental setup where charged particles (electrons or protons) are first accelerated by an electric field and then injected into a region of constant magnetic field with a field strength of 0.25 T. The potential difference required in the first part of the experiment is 9.57 kVPart (B) Find the radius of curvature, in meters of the path of a proton accelerated through this same potential after the proton crosses into the region with the magnetic field.Part (C) What is the ratio of the radii of curvature for a proton and an electron traveling through this apparatus?
