Question 5 POST_UTME_IGBINEDION_UNIVERSITY • 2019 • PHYSICS • objective

A radioactive sample has a half-life of $T_{1/2}$. If the initial number of nuclei is $N_0$, what is the number of nuclei remaining after a time $t$?

Answer Options

Correct Answer A. \( N = N_0 left\( \frac{1}{2} \right \ \)^{t/T_{1/2}})
B. \( N = N_0 left\( \frac{1}{2} \right \ \)^{T_{1/2}/t})
C. \( N = N_0 left\( \frac{1}{2} \right \ \)^{t/T_{1/2}^2})
D. \( N = N_0 left\( \frac{1}{2} \right \ \)^{T_{1/2}^2/t})
Correct Answer
A
Correct Option:
\( N = N_0 left\( \frac{1}{2} \right \ \)^{t/T_{1/2}})
