Answer» Correct Answer - B Since the radius of circualr path of charge particle of an magnetic field `r=(mv)/(qB)=(p)/(qB)` now the radius of circular path of charge particle of given mometum p and magnetic field B is given by `r prop (1)/(q)` But charge on both charge particles protons and deutones is same therefore `(r_(p))/(r_(d))=(q(d))/(q_(p))=1/1`
