An electron (mass m) with initial velocity v = v₀ i + v₀ j is in an electric field E = - E₀ k. If λ ₀ is initial de-Broglie wavelength of electron, its de-Broglie wave length at time t is given by:

(C) (λ ₀)/(√(1 + (e²E²t²)/(2m²v₀²)))

(A) (λ ₀)/(√(1 + (e²E²t²)/(m²v₀²)))

(B) (λ ₀ 2)/(√(1 + (e²E²t²)/(m²v₀²)))

(D) (λ ₀)/(√(2 + (e²E²t²)/(m²v₀²)))
