Which of the following is the correct relationship of half-life T₁/₂ and mean life τ [tau] of an unstable particle, if λ [lambda] is the decay constant?
W) T₁/₂ = λ/τ [Half-life equals lambda over tau];Χ) Τ₁/₂ = τ/λ [Half-life equals tau over lambda]
Y) T₁/₂ = τ log₂e [Half-life equals tau log base 2 of e];Ζ) Τ₁/₂ = τ ln(2) [Half-life equals tau natural log of 2]
✔️Answer:Z) T₁/₂ = τ ln(2)
