Problem

Let λe\lambda_e, λp\lambda_p and λd\lambda_d be the wavelengths associated with an electron, a proton and a deuteron, all moving with the same speed. Then the correct relation between them is (A) λd>λp>λe\lambda_d > \lambda_p > \lambda_e (B) λe>λp>λd\lambda_e > \lambda_p > \lambda_d (C) λp>λe>λd\lambda_p > \lambda_e > \lambda_d (D) λe=λp=λd\lambda_e = \lambda_p = \lambda_d
