MCQ
An electron with speed $v$ and a photon with speed $c$ have the same $de-Broglie$ wavelength. If the kinetic energy and momentum of electron are $E_{ e }$ and $pe _{ e }$ and that of photon are $E _{ ph }$ and $p _{ ph }$ respectively. Which of the following is correct?
- A$\frac{E_{e}}{E_{p h}}=\frac{2 c}{v}$
- ✓$\frac{E_{e}}{E_{p h}}=\frac{v}{2 c}$
- C$\frac{p_{e}}{p_{p h}}=\frac{2 c}{v}$
- D$\frac{ p _{ e }}{ p _{ ph }}=\frac{ v }{2 c }$
