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:
A
1: 3
B
3: 1
C
D
1: 1
Text Solution
Verified by ExpertsThe correct answer is:
D
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
