Question

what is the dimensional formula of gravitational constant ?

Answer 1

its value is 6.67×10^-11 N.m^2/Kg^2
dimensional formula thus M^-1 L^3 T^-2

Answer 2

HEYA!!
----------

$= > universal \: gravitational \: constant \: =$
G = Fd^2 / M1 • M2


Here ,

➡Dimensions of Force F = [ MLT^-2 ]

➡Dimensions of distance D = [ L^2 ]

➡Dimensions of Mass M = [ M^2 ]


So the Dimensions o f G =


G = [ MLT^-2 ] [ L^2 ] / [ M^2 ]

= [ M L ^3 T^-2 ] / [ M^2 ]

= [ M^ -1 L^3 T^-2 ]
