Expert Solution
Step 1

The concept of point masses in physics refers to objects that are modeled as having mass but no physical size. In other words, they are treated as mathematical points in space. In three dimensional space (R^3), a point mass can be described by its position in space, denoted by the vector Vj, and its mass, denoted by mj.
