What will be the speed of this recoiling nucleus if the speed of the alpha particle is 3.4×105 m/s ? assume the recoiling nucleu
s has a mass 57 times greater than that of the alpha particle?
1 answer:
here initially before the recoil of nucleus the system is considered to be at rest
now by the conservation of momentum we can say
now we know that
also it is given that
speed of alpha nucleus is 3.4 * 10^5 m/s
now by the momentum conservation equation we will have
so the recoil speed will be given as 5.9 * 10^3 m/s
