Figure 1 shows a hollow cylinder with diameter $$\(70 \mathrm{~cm}\)$$. The cylinder is rotating at a constant angular speed about its axis, which is vertical. As the cylinder rotates, a particle $$\(P\)$$ remains in contact with the same point on the rough inside surface of the cylinder. The particle is moving in a horizontal circle of diameter $$\(70 \mathrm{~cm}\)$$. The cylinder makes 2 complete revolutions every second. The coefficient of friction between $$\(P\)$$ and the cylinder is $$\(\mu\)$$. Find the range of possible values of $$\(\mu\)$$. (6)
