What is the unit c denotes here
F1 = G * m*m / [2r] ^2 = G * m^2 / 4r^2
Given the the mass is proportional to the volume and the volume is proportional to r^3, the mass of each big sphere is 3^3 = 27 times the mass of the small spheres. And the distance between the centers is 3r + 3r = 6r
F2 = G * [27m * 27m]/* [6r]^2 = G* 27^2 m^2 / 36r^2 = 81 G*m^2 / 4r^2 = 81*F1
Therefore, F2 = 81F1
Answer: option D) 81F1.
