Proton, deuteron and alpha particle of the same kinetic energy are moving in circular field. The radii of proton, deuteron and alpha particle are respectively rp, rd and rα. Which one of the following relations is correct?
The correct options are
We know that for proton, deuteron and alpha particle, mass ratio is 1:2:4 and charge ratio is 1:1:2.
which implies that r∝√mq
This results in : rα=rp<rd
