Question

find the wavelength of a hundred gram particle moving with a velocity of hundred metre per second​

Answer 1

Given:

The mass of particle, m = 100 gm = 0.1 kg

The velocity of particle, v = 100 m/s

To Find:

The wavelength of the particle, i.e., λ.

Calculation:

- The de Broglie wavelength of a particle can be given as follows:

λ = h/mv     (h is Plank's constant)

⇒ λ = 6.63 × 10⁻³⁴/ (0.1 × 100)

⇒ λ = 6.63 × 10⁻³⁵ m

- So, the wavelength of the given particle is 6.63 × 10⁻³⁵ m.

Answer 2

Answer:

the correct answer is 6.63×10-35
