The tube rotates at a constant angular velocity ω = 2 rad / s around the horizontal axis. A material point of mass m = 0.2 kg moves with the relative acceleration aτ = 4 m / s2 along the tube. Determine the modulus of force F at the time when l = 0.2 m, and the tube is in the vertical plane. (Answer 2.38)
