Find the dimensional formulae of the universal constant of gravitation G.

Asked 9 months ago By Shahid Anwar 0


Use:-

F=Gm1m2/r^2

Where, G=universal constant of gravitation, F=force, r=radius, m1, m2=mass.

Accepted Answer

Ans.     F=Gm1m2/r^2

or,        G=Fr^2 /m1m2

or,        [G] =[F]L^2 /M^2 =MLT^-2.L^2 /M^2  = M^-1L^3 T^-2.

Hence, the dimensional formula of universal constant of gravitation G, is [ M^-1L^3 T^-2]
