V. In a linear accelerator, protons are accelerated from rest in a uniform electric field, E= 8.65 x 100 V/m. It is directed along the y axis. Its displacement is 0.385 m in the direction of the field. (a) Determine the velocity of the protons after they are accelerated. fe = fc v=7.648 x10 m/s) Eq=mv² Ear m =V V= proton beam (8.65 x106) (1.6x10-19)(₁385) 9.11 X10-31 The proton beam enters a region of uniform magnetic field B. as shown above, that causes the beam to fol semicircular path. (b) Determine the magnitude of the magnetic field that is required to cause an arc of radius 0.10 meter. UP.
