The figure shows a region of length ' \( l \) ' with a uniform magnetic field of \( 0.3 \mathrm{~T} \) in it and a proton entering the region with velocity \( 4 \times 10^{5} \mathrm{~ms}^{-1} \) making an angle \( 60^{\circ} \) with the field. If the proton completes 10 revolution by the time it cross the region shown, ' \( I \) ' is close to (mass of proton \( =1.67 \times 10^{-27} \mathrm{~kg} \), charge of the proton \( = \) \( \left.1.6 \times 10^{-19} \mathrm{C}\right) \)
