Physics
Two uniform spheres, each of mass 0.260 kg, are fixed at points a and b. find the magnitude of the initial acceleration (in 10-10 m/s2 ) of a uniform sphere with mass 0.010 kg if released from rest at point p and acted on only by forces of gravitational attraction of the spheres at a and b.

Hey
Your answer is the one on the bottom
Newton's first law states that objects in motion will remain in motion (unless acted on by an external force) and that objects at rest will remain at rest.
On earth, if you throw a ball it will hit the ground and the friction between the grass and ball will slow it down. If the ground was frictionless then it would keep going forever.
