Question

Proton, Deuteron and alpha particle of the same kinetic energy are moving in circular trajectories in a constant magnetic field. The radii of proton, deuteron and alpha particle are respectively $r_{p}, r_{d}$ and $r_{α}$ . Which one of the following relations is correct?

Options:

Answer:

B

Solution:

$r = \frac{2 m K}{Bq}$ $r \propto \frac{m}{q}$ $r_{α} = r_{p} < r_{d}$
