The de-Broglie wavelength of a photon is twice, the de-Broglie wavelength of an electron. The speed of the electron is \( v_{e}=\frac{c}{100} \). Then,
(A) \( \frac{E_{e}}{E_{p}}=10^{-4} \)
(B) \( \frac{\mathrm{E}_{e}}{\mathrm{E}_{p}}=10^{-2} \)
(C) \( \frac{p_{e}}{m_{p} c}=10^{-2} \)
(D) \( \frac{p_{e}}{m_{e} c}=10^{-4} \)
