An electron , a proton a deutron and alpha -particle have the same kin

1.	An electron , a proton a deutron and alpha -particle have the same kinetic energy . Which of these particlehas the larger momentum ?
Answer» <P>an ELCTRON a proton a DEUTRON `alpha ` - particle Solution :Kinetic energy `K = (p^(2))/(2m)` K = constant, `p prop sqrt(m)` ` :. ` if mass is more its LINEAR momentum is more . Here `alpha ` - particle have more mass so its linear momentum is more .
