SUMMARY
The discussion centers on determining the magnitude and direction of a uniform magnetic field required to keep a proton undeflected while it moves through a uniform electric field. Given the proton's mass of 1.67 x 10^-27 kg and charge of +1.6 x 10^-19 C, with a velocity of 5.0 x 10^4 m/s in the x-direction and an electric field of 390 V/m in the y-direction, the magnetic field must counteract the electric force. The necessary magnetic field can be calculated using the formula B = E/v, resulting in a magnetic field of 7.8 x 10^-3 T directed in the negative z-direction.
