\mathrm{i}=\frac{\mathrm{q}}{\mathrm{dt}} \\

\mathrm{\mathrm{v}=\sqrt{2 \mathrm{gh}} \\ }

\mathrm{ \mathrm{m} \cdot \sqrt{2 \mathrm{gh}}=\mathrm{F} \cdot \mathrm{dt} }

\mathrm{ \mathrm{m} \cdot \sqrt{2 \mathrm{gh}}=\mathrm{i} / \mathrm{Bdt}=\frac{\mathrm{q}}{\mathrm{dt}} l \mathrm{Bdt} \\ }

\mathrm{ \mathrm{q}=\frac{\mathrm{m} \sqrt{2 \mathrm{gh}}}{\mathrm{B} l} }
