Atomic Structure Question 407

Question: If the de-Broglie wavelength of a particle mass m is 100 times its velocity, then its value in terms of its mass (m) and Planck’s constant (h) is

Options:

A) 110mh

B) 10hm

C) 110hm

D) 10mh

Show Answer

Answer:

Correct Answer: B

Solution:

  • Let wavelength of particle be x So, velocity (v)=x100

λ=hmv;,x=h×100m×x

x2=100hm or x=10hm
