An electron is accelerated from rest through a potential difference \(V\).

Which of the following is the de Broglie wavelength of the electron after acceleration?

A.     \(\frac{h}{{\sqrt {2{m_{\text{e}}}Ve} }}\)

B.     \(\sqrt {\frac{{2{m_{\text{e}}}h}}{{{V^2}}}} \)

C.     \(\frac{h}{{2{m_{\text{e}}}{V^2}{e^2}}}\)

D.     \(\frac{{{V^2}}}{{2{m_{\text{e}}}h}}\)
