Two particles of masses $\displaystyle \mathrm{m}_{1}$ and $\displaystyle \mathrm{m}_{2}$ having charges $\displaystyle \mathrm{q}_{1}$ and $\displaystyle \mathrm{q}_{2}$ respectively are projected with the same velocity in a region of uniform magnetic field $\displaystyle \vec{B}$ pointing vertically upward. If they describe circular paths as shown in the figure, one may conclude that :

From CBSE’s own marking scheme for this paper.
(C)
$\displaystyle \frac{\mathrm{m}_{1}}{\mathrm{~m}_{2}}<\frac{\mathrm{q}_{1}}{\mathrm{q}_{2}}$
