When a particle of charge q and momentum p enters a

Chapter 29, Problem 86GP

(choose chapter or problem)

When a particle of charge q and momentum  enters a uniform magnetic field at right angles it follows a circular path of radius \(R=p / q B\), as shown in Figure 29-32. What radius does this expression predict for a proton traveling with a speed \(v=0.99 c\) through a magnetic field \(B=0.20 T\) if you use

(a) the nonrelativistic momentum \((p=m v)\) or

(b) the relativistic momentum \(\left(p=m v / \sqrt{1-v^{2} / c^{2}}\right)\)?
