An electron moves at speed 8 . 0 times 1 0 6 ?m / s toward the
Question:
An electron moves at speed times ?ms toward the velocity selector shown in Figure ?where the electric field is hidden from view. A ?T magnetic field points into the paper.
A ?Determine the magnitude of the magnetic force that the magnetic field exerts on the electron.
B ?Determine the direction of the magnetic force that the magnetic field exerts on the electron? Upward or downward
C What E ?field magnitude is required so that the electric force exerted on the electron is equal in magnitude and opposite in direction to the magnetic force?
D ?What E ?field direction is required so that the electric force exerted on the electron is equal in magnitude and opposite in direction to the magnetic force? upwards or downwards
