Question 59

Medium

An alpha particle (mass $4 m$ , charge $2 e$ ) moves at a speed $v$ perpendicular to a uniform magnetic field of flux density $B$ . The radius of its circular path is $R$ .

A deuteron (mass $2 m$ , charge $e$ ) moves at a speed $2 v$ perpendicular to a uniform magnetic field of flux density $3 B$ .

What is the radius of the circular path of the deuteron in terms of $R$ ?

$43R\frac{4}{3}R$

$34R\frac{3}{4}R$

$23R\frac{2}{3}R$

$32R\frac{3}{2}R$
