Physics

An electron in a TV camera tube is moving at 7.20×106m/s in a magnetic field of strength 59 mT.Without knowing the direction of the field, what can you say aboutthe greatest and least magnitude of the force acting on theelectron due to the field? Maximum force?

Minimum force?

At one point the acceleration of the electron is6.327×1016 m/s2. What is the anglebetween the electron velocity and the magnetic field? (deg)
