# The dimensional formula for universal gravitational constant is:

${ M }^{ -1 }{ L }^{ 3 }{ T }^{ -2 }$

##### SOLUTION

The correct option is $D.$

Formula for Gravitational force is:

$F= \dfrac{G M m}{r^{2}}$

So, Formula for G will be,

$G = \dfrac{F r^{2}}{M m}$

Thus, the dimensional formula for G is,

$M^{-1}L^{3}T^{-2}$

You're just one step away
