Question

The charge flowing in a conductor changes with time as $\mathrm{Q}(\mathrm{t})=\alpha \mathrm{t}-\beta \mathrm{t}^2+\gamma \mathrm{t}^3$. Where $\alpha, \beta$ and $\gamma$ are constants. Minimum value of current is:

Select the correct option:

$\alpha-\frac{3 \beta^2}{\gamma}$

$\alpha-\frac{\gamma^2}{3 \beta}$

$\beta-\frac{\alpha^2}{3 y}$

$\alpha-\frac{\beta^2}{3 y}$
