An electron is accelerated through 2.4 x 10(adsbygoogle = window.adsbygoogle || []).push({}); ^{5}V from rest and then enters a uniform 1.7 T magnetic field. What are the maximum and minimum values of the magnetic force this particle

experiences?

QV = 0.5mv^{2}

F=QvB

Basically, I've got a final value from the above equations, but I'm not sure how to get a maximum and minimum as the problem states. The first equation gives me a speed of 2.9*10^{8}

and then putting that into F=QvB gives me a force of 7.89*10^{11}N.

Is this the maximum? Why do a maximum and minimum occur, and how do I calculate them?
