STANDARD Physics de-Broglie Wavelength MCQ Question
Type: MCQ-numerical-Medium
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 Planck's constant h is
A
1/10 √(m/h)
B
10 √(h/m)
C
1/10 √(h/m)
D
10 √(m/h)
Correct Answer
Option B
Detailed Explanation
Let the wavelength of the particle be x. Then, velocity = x/100. Using λ = h/mv, we have x² = 100 × h/m, or x = 10 √(h/m).
