Question

An electron in a TV camera tube is moving at 5.80×106 m/s in a magnetic field of strength 93 mT. Without knowing the direction of the field, what can you say about the greatest and least magnitude of the force acting on the electron due to the field?

Maximum force? (in N)

Minimum force? (in N)
