Two protons are having same kinetic  energy. One proton enters a uniform magnetic field at right angles  ot it. Second  proton enters a uniform electric field in the direction of field. After some time their de Broglie wavelengths are `lambda_1 and lambda_2` then (a) `lambda_1 = lambda_2` (b) `lambda_1 lt lambda_2` (c) `lambda_1 gt lambda_2` (d) some  more information is required
