The figure shows a region of length '$\ell$' with a uniform magnetic field of 0.3 T in it and a proton entering the region with velocity 4×105 ms-1 making an angle 60º with the field. If the proton completes 10 revolution by the time it cross the region shown, '$\ell$' is close to (mass of proton = 1.67 × 10-27 kg , charge of the proton = 1.6 × 10-19 C)
