Two electrons are moving with non-relativistic speed perpendicular to each other. If corresponding de Broglie wavelength are λ ₁ and λ ₂, their de Broglie wavelength in the frame of reference attached to their center of masses:

(B) λ CM = (2λ ₁λ ₂)/(√(λ ₁² + λ ₂²))

(C) 1/(λ CM) = 1/(λ ₁) + 1/(λ ₂)

(D) λ CM = ((λ ₁ + λ ₂)/2)
