3. Suppose there is a mass M₁ at the origin and a mass M₂ at (3,0,0). The combined gravitational field from both masses will be the sum of the individual fields that each of them create. a. What is the flux of the gravitational field out of the surface of a sphere of radius 6 centered at the origin? b. What is the flux of the gravitational field out of the surface of a sphere of radius 2 centered at the origin?
