Question: A proton follows a spiral path through a gas in a magnetic field of 0.010T, perpendicular to the plane of the spiral, as shown in

A proton follows a spiral path through a gas in a magnetic field of 0.010T, perpendicular to the plane of the spiral, as shown in Fig. 20-70, in two successive loops, at points P and Q, the radii are 10.00mm and 8.5mm, respectively. Calculate the changes in the kinetic energy of the proton as it travels from P to Q.
