The time dependence of a physical quantity $P$ is given by $P = P_{0} e_{α} (- α t^{2})$ , where $α$ is a constant and $t$ is time. The constant $α$

Options:

Answer:

Solution:

Given, $P = P_{0} exp (- α t^{2})$ As $P$ and $P_{0}$ have the same units, therefore $α t^{2}$ must be dimensionless for which $α = \frac{1}{T ^{2}} = T^{- 2}$
