The potential energy of a point particle is given by the expression $V(x)=-\alpha x+\beta \sin (x / \gamma)$. A dimensionless combination of the constants $\alpha, \beta$ and $\gamma$ is
$\frac{\alpha}{\beta \gamma}$
$\frac{\alpha^2}{\beta \gamma}$
$\frac{\gamma}{\alpha \beta}$
$\frac{\alpha \gamma}{\beta}$
In the following list, the only pair which have different dimensions, is
Which one has the dimensions different from the remaining three
The dimensional formula $[ML^0T^{-3}]$ is more closely associated with
A force is represented by $\mathrm{F}=a \mathrm{x}^2+\mathrm{bt}^{1 / 2}$. Where $\mathrm{x}=$ distance and $\mathrm{t}=$ time. The dimensions of $\mathrm{b}^2 / \mathrm{a}$ are :
If the dimensions of a physical quantity are given by $M^aL^bT^c$ ,then physical quantity will be
