Question 107

An alpha particle (mass 4m4m4m, charge 2e2e2e) moves at a speed vvv perpendicular to a uniform magnetic field of flux density BBB. The radius of its circular path is RRR.

A deuteron (mass 2m2m2m, charge eee) moves at a speed 2v2v2v perpendicular to a uniform magnetic field of flux density 3B3B3B.

What is the radius of the circular path of the deuteron in terms of RRR?

A

43R\frac{4}{3}R34​R

B

34R\frac{3}{4}R43​R

C

23R\frac{2}{3}R32​R

D

32R\frac{3}{2}R23​R
