With the usual notations, the following equation ${S_t} = u + \frac{1}{2}a(2t – 1)$ is

If energy $(E),$ velocity $(V)$ and time $(T)$ are chosen as the fundamental quantities, the dimensional formula of surface tension will be

If the buoyant force $F$ acting on an object depends on its volume $V$ immersed in a liquid, the density $\rho$ of the liquid and the acceleration due to gravity $g$. The correct expression for $F$ can be

If orbital velocity of planet is given by $v = {G^a}{M^b}{R^c}$, then
