Q6. A nucleus disintegrates into two nuclear parts, in such a way that ratio of their nuclear sizes is 1 : 21/3 . Their respective speed have a ratio of n : 1 . The value of n is_________
What This Question Tests
This question combines the nuclear radius relation (R ∝ A^(1/3)) to find the ratio of masses with the principle of conservation of momentum during nuclear disintegration to determine the ratio of speeds.
Concepts Tested
Formulas Used
R = R₀A^(1/3)
