1.A proton enters a 2.0 X 10^-2 T magnetic field with a speed of 5.8 X 10^4 m/s. What is the radius of the circular path it follows?
formula??
2.Electrons moving at 3.5 X 10^4 m/s pass through an electric field with an intensity of 5.6 X 10^3 N/C. How large a magnetic field must the electrons also experience for their path to be undeflected?
formula??

You can derive this by setting centripetal force=magnetic force
mv^2/r=qBv
