Homework Statement
The gravitational force between two shperes is 2.50x10^-8. Their centers are 105 cm apart. The larger sphere has a mass of 8.20 kg. Find the mass of the smaller sphere.
Homework Equations
F=Gm1m2/d²
The Attempt at a Solution
F=Gm1m2/d²
d² x F=Gm1m2/d² x d²
Fd²=Gm1m2
Fd²/Gm1=Gm1m2/Gm1
Fd²/Gm1=m2
m2=((2.50x10^-8 N)(105² cm))/((6.67x10^-11 Nm²/kg²)(8.20 kg))
m2=5.04x10^5 kg
That can't be right because the missing mass is supposed to be smaller than 8.20 kg. Did I move the equation around right?
