**drwls**, Monday, January 18, 2010 at 11:10amUse Newton's universal law of gravity.

F = G M1 M2/R^2

In this case, M2 = 2 M1. Therefore

F = 2 M1^2/R^2.

M1 is the mass of the smaller sphere. R is the separation. Look up the universal constand G; it must be in your notes, or textbook.

Solve for the smaller mass, M1. Double that for M2. Show your work if further help is needed.
