10.1 Three uniform spheres with masses m1 = 6.0 kg, m2 = 2.0 kg ,
and m3 = 4.0 kg are fixed at the positions shown in the diagram.
Assume they are completely isolated and there are no other masses
nearby.

(a) What is the magnitude of the acceleration on a particle placed at
the origin (Point P)? What is the direction of this acceleration?
b) For a particle at point P, what speed is required for it to
completely escape the gravitational attraction of the three fixed
masses?
(c) How much energy is required to separate the three masses so
that they are very far apart?
