An electron of mass m and having an initial velocity →v=v0 ^i (v0>0) – InterviewSolution

1.	An electron of mass m and having an initial velocity →v=v0 ^i (v0>0), enters an electric field →E=−E0^i (E0 (constant)>0) at t=0. If λ0 is its de-Broglie wavelength initially, then its de-Broglie wavelength after time t is,
Answer» An electron of mass $m$ and having an initial velocity $\to v = v_{0}^i (v_{0} > 0)$ , enters an electric field $\to E = - E_{0}^i (E_{0} (constant) > 0)$ at $t = 0$ . If $λ_{0}$ is its de-Broglie wavelength initially, then its de-Broglie wavelength after time $t$ is,
