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