Which of the following is the correct equation for the law of radioactive decay? Symbols have their usual meaning.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → $N(t)=N_oe^{-λt}$
The radioactive decay formula is given by -
$N=N_0e^{-λT}$
where,
N → Quantity still remained
$N_0$ → Initial Quantity
T → Half-life of decay Quantity
