An electron (mass m) with an initia velocity v^{\to}=v_0i^{\^} in an electric field E^{\to}=E_0j^{\^}. If \lambda_0=h/{mv_0}, its de Broglie wavelength at time t is given by

Correct Answer is : λ0√1+e2E02t2m2v02

\lambda_0\sqrt{1+\frac{e^2E_0^2t^2}{m^2v_0^2}}

\lambda_0/\sqrt{1+\frac{e^2E_0^2t^2}{m^2v_0^2}}

\lambda_0/ {1+\frac{e^2E_0^2t^2}{m^2v_0^2}}
