JEE MAIN - Physics (2021 - 25th July Morning Shift - No. 5)
A particle of mass 4M at rest disintegrates into two particles of mass M and 3M respectively having non zero velocities. The ratio of de-Broglie wavelength of particle of mass M to that of mass 3M will be :
1 : 3
3 : 1
1 : $$\sqrt 3 $$
1 : 1
Explanation
$$\lambda = {h \over p}$$
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
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
