A deuteron and an alpha particle having same momentum are in turn allowed to pass through a magnetic field , acting normal to the direction of motion of the particles. Calculate the ratio of the radii of the circular paths described by them.
We know that deuteron has charge of +e and mass where
is the mass of the proton,
Similarly,
- particle has charge of
and mass
.
The radius of the circular path
Since momentum are same (given in the question) and B is also constant,
therefore
