1. The problem statement, all variables and given/known data 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. 2. Relevant equations F=Gm1m2/d² 3. 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?
