APFIVE Force on an Axis of Rotation
Two masses, m₁ and m₂, are connected by a massless rod of length L. The system rotates at a constant angular velocity ω about an axis perpendicular to the rod and passing through m₁. If m₂ = 3m₁, what external force must be applied to m₁ to keep the system in translational equilibrium?
A
3m₁ω²L directed toward m₂
B
3m₁ω²L directed away from m₂
C
4m₁ω²L directed away from m₂
D
m₁ω²L directed away from m₂
