Question

A uniform sphere with mass 60.0 kg is held with its center at the origin, and a second uniform sphere with mass 90.0 kg is held with its center at the point x = 0, y = 3.00 m. A third uniform sphere with mass 0.600 kg placed at the point x = 4.00 m, y = 0.

A) What is the magnitude of the net gravitational force due to 60.0 kg and 90.0 kg spheres on 0.600 kg sphere.

B) What is the direction of the net gravitational force due to 60.0 kg and 90.0 kg spheres on 0.600 kg sphere.

C) Where, other than infinitely far away, could the third sphere be placed such that the net gravitational force acting on it from the other two spheres is equal to zero?
