Question

A nucleus ruptures into two nuclear parts, which have their velocity ratio equal to 2 : 1. What will be the ratio of their nuclear size (nuclear radius)?

(a) 3^1/2 : 1

(b) 1 : 3^1/2

(c) 2^1/3 : 1

(d) 1 : 2^1/3

Answer 1

The correct option is (d) 1 : 2^1/3.

Explanation:

Velocity ratio (v₁ : v₂) = 2 : 1. 

Mass (m) ∝ volume ∝ r³

According to law of conservation of momentum
