Two particles $A$ and $B$ of masses ${m_A}$ and ${m_B}$ respectively and having the same charge are moving in a plane. A uniform magnetic field exists perpendicular to this plane. The speeds of the particles are ${v_A}$ and ${v_B}$ respectively, and the trajectories are as shown in the figure. Then
  • A${m_A}{v_A} < {m_B}{v_B}$
  • B${m_A}{v_A} > {m_B}{v_B}$
  • C${m_A} < {m_B}\,\,{\rm\,{and }}\,\,{v_A} < {v_B}$
  • D${m_A} = \,{m_B}\,{\rm\,{and \,}} {v_A} = {v_B}$
