Question

the reduced mass of 2 particles having masses m and 2m is??

Answer 1

reduced mass of particle = μ= m1 m2/ m1 + m2

In this condition m1= m
and m2 = 2m

putting the value in the equation

μ= m x 2m/ m + 2m
= 2m²/ 3m
= 2m/3

This is the reduced mass  

Answer 2

reduced mass of particle = μ= m1 m2/ m1 + m2

In this condition m1= m

and m2 = 2m

putting the value in the equation

μ= m x 2m/ m + 2m

= 2m²/ 3m

= 2m/3

This is the reduced mass
