How does doubling the mass of a rotating sample change the centrifugal force on it?

Doubling the mass of a rotating sample increases the centrifugal force acting on it by a factor of 2.

This is because the centrifugal force is directly proportional to the mass of the object being rotated. In the context of a centrifuge, the force ($F$) is expressed by the relation $F=\frac{m{v}^2}{R}$, where $m$ represents mass, $v$ represents speed, and $R$ represents the radius of the circular path. Because mass appears as a linear factor in this equation, any change in mass results in a proportional change in the total force exerted.12
