Question: A proton is accelerated from rest through a potential difference of 0.5MV.
a. What is its kinetic energy after this acceleration?
b. What is its velocity?
c. If it enters, as shown in Fig., a uniform magnetic field of 0.1T, pointing into the plane of the paper, does the proton's path curve toward the top edge of the page or toward the bottom edge?
d. What is the radius of curvature of its path in the magnetic field?
