A proton,moving in a uniform magnetic field,moves in a circle perpendicular to the $\vec { B }$ field lines and takes time T for each circle.If the proton's speed tripled,what would now be its time to go around each circle?

Question

Quizplus · Accepted Answer

The time to go around each circle (period) for a charged particle in a magnetic field is independent of its speed, as it depends only on the charge, mass of the particle, and the magnetic field strength.
