A nucleus at rest disintegrates into two smaller nuclei with their masses in the ratio of

2: 1

. After disintegration they will move :-

[9 Apr 2024 Shift 2]

In opposite directions with speed in the ratio of $1: 2$ respectively
In opposite directions with speed in the ratio of $2: 1$ respectively
In the same direction with same speed.
In opposite directions with the same speed.

Solution: 👈: Video Solution

By conservation of momentum

\; p_i = p_f

\; O = m_1 u_{1+} m_2 u_2

\;\; \frac{u_1}{u_2} = - \left[ \;\frac{1}{2} \right] \;\text{ as }\; \; \frac{m_1}{m_2} = \frac{2}{1}

move in opposite direction with speed ratio

1: 2
