Question

The following particles are moving with
same velocity. The particle with maximum
momentum is :​

Answer 1

Answer:

Explanation:

If particles are moving with the same velocity, then what is maximum de Broglie wavelength for?

Formula for de Broglie wavelength is, λ=hp

where h=Planck’s constant and p=mv which is linear momentum

Therefore

λ=hmv

If v is constant then, λα1m

Thus wavelength will be inversly proportional to mass.

So the particle having higher mass will have lower wavelength and vice-versa.

So alpha particle has the highest momentum.
