If the de-broglie wavelength of a particle of mass $(m)$ is 100 times its velocity. Then, its value in terms of its mass $(m)$ and plank constant $(h)$ is

Options:

Answer:

Solution:

Let the wavelength of given particle $= x$ Velocity $(v) = \frac{x}{100}$ Using wavelength formula $λ = \frac{h}{m v} ∴ x x^{2} \Rightarrow x x = \frac{h}{m ( \frac{x}{100} )} = \frac{100 h}{m x} = 100 \frac{h}{m} = 10 \frac{h}{m}$
