∴G=F.r^2/M.G=6.533*10^(-11)Nm^2/kg^2.......
A shape of mass 40 kg is attracted by another shape of mass 15 kg with a force 1/10 m gf. Find the constant of gravitation if the centers of the spheres are 20 cm apart.

-
M=40 kg.

m=15 kg.

F=9.8*10^(-7)

R=20/100

=0.2m




Since,


F=G[Mm]/R^2

∴G=F.r^2/M.m

Aftermath;

G=6.533*10^(-11)Nm^2/kg^2.
