Question

if the de Broglie wavelength of a particle of mass M is 100 times its velocity then its value on the terms of its mass and Planck's Constant h s

Answer 1

use p=h/mv . p::::> Planck constant

Answer 2

let  the wavelenght of the particle be =ₓ

so the velocity =ₓ÷100

lambda=height÷mass×velocity

ˣ=h×100÷m×x

x∧2=100h÷m

x=10√h/m
