Question

Two radioactive elements $A$ and $B$ initially have same number of atoms. The half life of $A$ is same as the average life of $B$. If $\lambda_A$ and $\lambda_B$ are decay constants of $A$ and $B$ respectively, then choose the correct relation from the given options.

Accepted Answer

Answer

$\lambda_A \ln 2=\lambda_B$

Answer

$\lambda_{\mathrm{A}}=\lambda_{\mathrm{B}}$

Answer
