A proton (p = +, mp = 1.0 u; where u = unified mass unit ≃ 1.66 × 10−27kg), a deuteron ( = +, m = 2.0 u) and an alpha particle ( = +2, m = 4.0 u) are accelerated from rest through the same potential difference , and then enter the same region of uniform magnetic field ⃗⃗ , moving perpendicularly to the direction of the magnetic field.
a. What is the ratio of the proton’s kinetic energy Kp to the alpha particle’s kinetic energy K
b. What is the ratio of the deuteron’s kinetic energy K to the alpha particle’s kinetic energy K
c. If the radius of the proton’s circular orbit p = 10 cm, what is the radius of the deuteron’s orbit
d. What is the radius of the alpha particle’s orbit
