Two uniform spheres, each of mass $0.260 \mathrm{kg},$ are fixed at points $A$ and $B$ (Fig. E13.5). Find the magnitude and direction of the initial acceleration of a uniform sphere with mass 0.010 $\mathrm{kg}$ if released from rest at point $P$ and acted on only by forces of gravitational attraction of the spheres at $A$ and $B .$

Key Concepts

Newton's Law of Universal Gravitation

This law states that every two point masses attract each other with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between them. It forms the basis for calculating the gravitational pull between any two objects, and in problems involving uniform spheres, the objects can be treated as point masses located at their centers.

Superposition Principle for Gravitational Forces

This principle asserts that the total gravitational force acting on an object is the vector sum of the individual forces exerted by each separate mass. It allows one to calculate the net gravitational influence on an object when multiple bodies are involved, by considering each gravitational force independently and then combining them.

Newton's Second Law of Motion

Newton's Second Law of Motion establishes the relationship between force, mass, and acceleration, expressed by F = ma. This law enables the determination of an object's acceleration when the net force acting on it is known, making it essential for translating calculated gravitational forces into motion results.
