Unformatted text preview: . cm 2 R ρVω d) If , ob cm R cmob R ρ ρ the inward force is greater than that needed to keep the object moving in a circle with radius cmob R at angular frequency ω , and the object moves inward. If , ob cm cmob R ρ ρR < , the net force is insufficient to keep the object in the circular motion at that radius, and the object moves outward. e) Objects with lower densities will tend to move toward the center, and objects with higher densities will tend to move away from the center....
