MCQ
A proton and a deutron both having the same kinetic energy, enter perpendicularly into a uniform magnetic field B. For motion of proton and deutron on circular path of radius $R_p$ and $R_d$ respectively, the correct statement is
  • $R_d=\sqrt{2} R_p$
  • B
    $R_d=R_p / \sqrt{2}$
  • C
    $R_d=R_p$
  • D
    $R_d=2R_p$

Answer

Correct option: A.
$R_d=\sqrt{2} R_p$
(a) $R_d=\sqrt{2} R_p$
