Problem
Two protons have the same kinetic energy. One proton enters a uniform magnetic field at right angles to it. The second proton enters a uniform electric field in the direction of the field. After some time their de Broglie wavelengths are λ1 and λ2, respectively. Then
(1) λ1=λ2
(2) λ1<λ2
(3) λ1>λ2
(4) Some more information is required
