An electron (mass {\m} ) with an initial velocity \overrightarrow{v}=v_0 i(v_0 > 0) is moving in an electric field \overrightarrow{E}=-E_0 \stackrel{\^}{i}(E_0 > 0) where E_0 is constant. If at {\t}=0 de Broglie wavelength is \lambda_0=\frac{h}{m v_0}, then its de Broglie wavelength after time t is given by [27-Jul-2022-Shift-1]

Correct Answer is : λ0(1+eE0tmv0)

\lambda_0(1+\frac{e E_0 t}{m v_0})

{\lambda_0}/{(1+\frac{e E_0 t}{m v_0})}
