A proton moves through a magnetic field of 0.3 T and has an electric field of strength 1000 N/C acting on it. Calculate the velocity of the proton required for it to move in a straight line.
💡 Hint: Use the relationship that allows you to solve for velocity.
If a velocity selector is set to filter particles at a speed of 200 m/s, what electric field strength is required if the magnetic field is 0.2 T?
💡 Hint: Think about how the electric field relates to the velocity of the particles.
