Question

if the radius of circular path Proton is 10 centimetre what are the radii of deuteron and Alpha particle​

Answer 1

A proton, deuteron, and an alpha particle in a region with a uniform magnetic field each follow circular paths that have the same radius. The deuteron has a charge that is equal to the charge a proton has, and an alpha particle has a charge that is equal to twice the charge a proton has. Assume that m = 2md = 4mp.
