An alpha particle (consisting of two protons and two neutrons), traveling at a speed of v = 1.9 x 105 m/s, enters a region of constant magnetic field of strength B = 1.9 T as shown in the figure. The direction of B is out of the image. The alpha follows a path that is a circular arc of radius r.

 

Part (a)  In atomic mass units, what is the mass m of an alpha particle? 
Part (b)  In units of elementary charge e, what is the electric charge q of an alpha particle? 
Part (c)  In meters, what is the radius of curvature r of the path taken by the alpha particle?

A proton (charge +e, mass mp), a deuteron (charge +e, mass 2mp), and an alpha particle (charge +2e, mass 4mp) are accelerated from rest through a common potential difference V. Each particle enters a uniform magnetic field B, with its velocity in a direction perpendicular to the magnetic field. The proton moves in a circular path of radius rp. In terms of rp, what is the radius rd of the circular orbit of the deuteron and radius ra of the alpha particle?
