Part A
The two spheres A and B each have a mass of 400 g. The spheres are fixed to the
horizontal rods as shown in (Figure 1) and their initial velocity is 2 m/s. The mass of the
supporting frame is negligible and it is free to rotate. Neglect the size of the spheres.
If a couple moment of M = 0.9 N m is applied to the frame, determine the speed of the spheres in 3 s.
Express your answer to three significant figures and include the appropriate units.

Consequently, there should be a "Gauss's law for gravity." Part A The electric field was defined as E = Fon g/g, and we used this to find the electric field of a point charge. Using analogous reasoning, what is the gravitational field g of a point mass? Write your answer using the unit vector r, but be careful with signs; the gravitational force between two "like masses" is attractive, not repulsive. Express your answer in terms of the variables M, r, unit vector î, and the gravitational constant G.
