An electron is accelerated through 1800V from rest and then enters a uniform 2.90T magnetic field. What are the maxium and minium values of the magnetic force this charge can experience?(adsbygoogle = window.adsbygoogle || []).push({});

Ok someone help me out here...not sure of the equation. How do the formulas for a magnetic force differ between a line of current and a moving charge?

In this case I believe the formula is Fm=QVBsin(theta). The maxium & minium force will vary with the angle measure, i.e. sin(90)=max. But how does potential difference (1800V) come in to play here? Where does the value of the magnetic field (B) come from?
