If \(E_p\) and \(E_e\) represent kinetic energy of photon and electron respectively. If de-Broglie wavelength \(\lambda_p\) of a photon is twice the de-Broglie wavelength \(\lambda_e\) of electron, then \(E_e / E_p\) is (Speed of electron \(=\frac{\mathrm{C}}{100}\), where 'C' is the velocity of light)
- A \(2 \times 10^{-2}\)
- B \(1 \times 10^{-2}\)
