Question

Statement I A nucleus having energy E₁ decays be β^- emission to daughter nucleus having energy E₂, but β^- rays ere emitted with a continuous energy spectrum having end point energy E₁ - E₂.

Statement II To conserve energy and momentum in β-decay, at least three particles must take part in the transformation.

(a) Statement I is false, Statement II is true

(b) Statement I is true, Statement II is false

(c) Statement I is true, Statement II is true; Statement II is the correct explanation of Statement I

(d) Statement I is true, Statement II is true; Statement II is not the correct explanation of Statement I

Answer 1

Correct Option (c) Statement I is true, Statement II is true; Statement II is the correct explanation of Statement I

Explanation:

In particle situation, at least three particles take place in transformation, so Energy of β-particle + Energy of third particle
