PhysicsEasy145×since 2002Q6545An electron of mass m and magnitude of charge |e| initially at rest gets accelerated by a constant electric field E. The rate of change of de-Broglie wavelength of this electron at time t ignoring relativistic effects is :A−h∣e∣Et{{ - h} \over {\left| e \right|Et}}∣e∣Et−hB−h∣e∣Et{{ - h} \over {\left| e \right|E\sqrt t }}∣e∣Et−hC−h∣e∣Et2{{ - h} \over {\left| e \right|E{t^2}}}∣e∣Et2−hD∣e∣Eth{{\left| e \right|Et} \over h}h∣e∣EtCheck answerSkip
