Question

If a nucleus at rest disintegrates into two smaller nuclei, the products must be emitted in opposite directions. Explain?

Answer 1

because it will emit alpha n beta particles... alpha particles are positively charged n beta particle's are negatively charged...the alpha particles will go towards the negative plate...n beta particles will go towards the positive plate

Answer 2

Let m, m1, and m2 be the respective masses of the parent nucleus and the two daughter nuclei.

The parent nucleus is at rest.

Initial momentum of the system (parent nucleus) = 0

Let v1 and v2 be the respective velocities of the daughter nuclei having masses m1 and m2.

Total linear momentum of the system after disintegration = m1v1= m2v2

According to the law of conservation of momentum:

Total initial momentum = Total final momentum

0= m1v1 + m2v2

v1 = (-m2v2)/(m1)

Here, the negative sign indicates that the fragments of the parent nucleus move in directions opposite to each other.

I hope, this will help you
