An electron of mass$m$with an initial velocity$\overrightarrow{V}=V_0\hat{\mathrm{i}}(V_0>0)$enters in an electric field$\overrightarrow{E}={\mathrm{-E}}_0\hat{\mathrm{i}}(E_0>0$and is a constant$)$at$t=0$. If${\lambda }_0$is its de-Broglie wavelength initially, then its de-Broglie wavelength at time$t$isNEET 2018
