If the dimensional formula of '(Energy $\times$ speed $)$ ' is $\left[\mathrm{M}^{\mathrm{a}} \mathrm{L}^{\mathrm{b}} \mathrm{T}^{\mathrm{c}}\right]$ then $\mathrm{a}, \mathrm{b}$ and $\mathrm{c}$ are
$(1,3,-3)$
$(1,2,2)$
$(1,2,3)$
$(1,3,-2)$
Solution
$[$ Energy $\times$ Speed $]=\mathrm{ML}^2 \mathrm{~T}^{-2} \times \mathrm{LT}^{-1}$
$=\mathrm{ML}^3 \mathrm{~T}^{-3}$
So, $a=1, b=3, C=-3$
