Two particles of masses $m_1$ and $m_2$ having charges $q_1$ and $q_2$ respectively are projected with the same velocity in a region of uniform magnetic field $\vec{B}$ pointing vertically upward. If they describe circular paths as shown in the figure, one may conclude that :
A
$\frac{m_1}{m_2} > \frac{q_1}{q_2}$
B
$\frac{m_1}{m_2} > \frac{q_2}{q_1}$
C
$\frac{m_1}{m_2} < \frac{q_1}{q_2}$
D
$\frac{m_1}{m_2} < \frac{q_2}{q_1}$
