If the proton starts from rest and accelerates 2.0 meters through an electric field strength of 2700 V/m, calculate the change in kinetic energy of the proton as it moves through the electric field.
2) find the speed of the proton as it enters the shaded region.
3) when the proton enters the magnetic field what is the direction of the magnetic force on the proton? Draw the path of the proton in the magnetic field.
4) find the radius of curvature of the proton in magnetic field.
A proton beam (mass m = 1.67 x 10^-27 kg and charge q = 1.6 x 10^-19 C) is accelerated starting from rest through a region of uniform electric field, and then enters a region of uniform magnetic field through a slit, as shown in the figure below. The magnetic field has a direction into the screen and a magnitude of 0.05 T.
