A proton (?? = +?, ?? = 1.0 u; where u = unified mass unit ≃1.66 × 10−27kg), a deuteron (?? = +?, ?? = 2.0 u) and an alphaparticle (?? = +2?, ?? = 4.0 u) are accelerated from rest throughthe same potential difference ?, and then enter the same region ofuniform magnetic field ?⃗⃗ , moving perpendicularly to thedirection of the magnetic field.
A) What is the ratio of the proton’s kinetic energy ?? to thealpha particle’s kinetic energy ???
B) What is the ratio of the deuteron’s kinetic energy ?? to thealpha particle’s kinetic energy ???
C) If the radius of the proton’s circular orbit ?? = 10 cm, whatis the radius of the deuteron’s orbit ???
D) What is the radius of the alpha particle’s orbit ???
