QJEEM22Phf70a: JEE Main 2022 Physics - Class 12 JEEM22Phf70a Solution: A nucleus of mass at rest splits into two parts having masses…

A nucleus of mass MM at rest splits into two parts having masses M′3\frac{M^{\prime}}{3} and {{2M'} \over 3}(M' < M) . The ratio of de Broglie wavelength of two parts will be :

Multiple Choice Options

  • A 1:02
  • B 2:01
  • C 1:01
  • D 2:03

Step-by-Step Verified Solution

Linear momentum is conserved

so, pM′/3=p2M′/3{p_{M'/3}} = {p_{2M'/3}}

so, λM′/3λ2M′/3=11{{{\lambda _{M'/3}}} \over {{\lambda _{2M'/3}}}} = {1 \over 1}
