Q1

A particle with initial velocity \({v}_{0}\)​ and charge q has an initial de Broglie wavelength \({\lambda }_{0}\)​. If an electric field \(\overset{⃗}{E}={E}_{0}\overset{^}{k}\) is present in space, find the de Broglie wavelength of the particle at time \(t\).

a

\(\frac{h}{m{v}_{0}−q{E}_{0}t}\)

b

\(\frac{h}{m{v}_{0}+q{E}_{0}t}\)

c

\(\frac{h}{m({v}_{0}+t{E}_{0})}\)

d

\(\frac{h}{m{v}_{0}}\)
