A proton travels between the two parallel charged plates shown in the figure. The plates are separated by 1.0 cm and are charged by a V battery. There is a magnetic field strength T which allows the proton to pass between the plates without being deflected. What is the speed of this proton in m/s? Ignore gravitational force.
