8. Centripetal Forces & Gravitation

In the context of mass distribution with calculus, which of the following physical quantities is directly affected by the distribution of mass in an object?

Given three groups of particles located along the x-axis: Group A consists of 5 particles each of mass $2$ kg at positions $0$ m, $1$ m, $2$ m, $3$ m, and $4$ m; Group B consists of 4 particles each of mass $3$ kg at positions $0$ m, $2$ m, $4$ m, and $6$ m; Group C consists of 6 particles each of mass $1.5$ kg at positions $0$ m, $1$ m, $2$ m, $3$ m, $4$ m, and $5$ m. Which group has the greatest total mass?
