Question:
A particle of mass $4 \mathrm{M}$ at rest disintegrates into two particles of mass $\mathrm{M}$ and $3 \mathrm{M}$ respectively having non zero velocities. The ratio of de-Broglie wavelength of particle of mass $M$ to that of mass $3 \mathrm{M}$ will be:
Correct Option: , 4
Solution:
$\lambda=\frac{h}{p}$
both the particles will move with momentum same in magnitude \& opposite in direction.
So De-Broglie wavelength of both will be same i.e. ratio $1: 1$
