A non-relativistic particle X is moving 2.24 times as fast as an electron. The ratio of their de Broglie wavelengths, particle to electron, is $2.24 \times 1 0^{- 4}$ . The particle X is

Options:

Answer:

Solution:

$\frac{λ _{X}}{λ _{e}} = \frac{m _{e} v _{e}}{m _{X} v _{X}} = \frac{1}{2.24} \cdot \frac{m _{e}}{m _{X}} = 2.24 \times 1 0^{- 4} \Rightarrow m_{X} = \frac{m _{e}}{2.2 4 ^{2} \times 1 0 ^{- 4}} \approx 1836 m_{e} -$ a proton.
