Four charge particles He++, proton, deutron and Li++ enters a region of uniform magnetic field and moves in a circular path of different radius. List I gives above four particles while list II gives magnitude of some quantity.
List IList III - He++P) 1II - ProtonQ) 2III - deutronR) 1√2IV) Li++S) √2T) √72U) 12
If kinetic energy of all four particles is same than correct match for radius of four particles in units of radius of proton is
