gravitational force of attraction between two spheres is 2.5x10^-8N. the centers are measured 105 cm apart. the one sphere has a mass of 8.2kg what is the mass of the other sphere? thanks :)

F=(GmM)/r^2 Newtons law of universal gravitation
Where,
F= 2.5x10^-8 N
G=6.64x10-11 Nm^2 kg^-2
m= 8.2 kg
M= ? kg
r= 1.05 m
Rearrange to make M the subject
F(r^2)/(Gm)=M
Now plug and chug!
