Two particles $A$ and $B$ of masses $m_A$ and $m_B$ respectively,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$m_A < m_B$ and $v_A < v_B$
- D$m_A = m_B$ and $v_A = v_B$
