An alpha-particle and a proton are fired...

An `alpha`-particle and a proton are fired through the same magnetic field which is perpendicular to their velocity vectors. The `alpha`-partcles and the proton move such that radius of curvature of their paths is same. Find the ratio of their de Broglie wavelengths.
