3 Charge Deflector E beam An experiment to look for a charge imbalance between the proton and electron is constructed as shown. A beam of particles moving at speed vo = 1.0 x 106 m/s is prepared in an accelerator. Before striking the detector, the beam passes through a region of length L = 10 m that contains a uniform electric field of strength & = 100 N/C perpendicular to the beam. (a) Where would a proton from the beam be expected to strike the detector? (L.e., how many meters above or below the beam line would it strike?) (b) Where would an electron from the beam be expected to strike the detector? (L.e., how many meters above or below the beam line would it strike?) (c) We do not believe a hydrogen atom has any charge, but an experiment can only put an upper limit on the net charge - not prove that it is zero. Suppose the detector in this experiment is unable to detect a deflection less than 1 nm. I.c., if the deflection is 1 nm or less, the detector will register "0" deflection.…
