In an experiment on the shuttle, an electron with a speed of 6.3 x 105 m/s [N] and a mass of 9.11 x 10-31 kg is shot through an external magnetic field. Determine the strength and orientation of the magnetic field required so that the electron's direction of travel remains unchanged. Neglect any effects due to the Earth's magnetic field.
1 answer
The magnetic field if aligned to the same direction as electron velocity, no force is on the electron, regardless of strength.
