Physics - Circular Motion Question with Solution | TestHub

In a rotor, a hollow vertical cyclindrical structure rotates about its axis and a person rests against the inner wall. At a particular speed of the rotor, the floor below the person is removed and the person hangs resting against the wall without any floor. If the radius of the rotor is 2 m and the coefficient of static friction between the wall and the person is 0.2 , find the minimum speed at which the floor may be removed. Take $\mathrm{g}=10\mathrm{m}/{\mathrm{s}}^2$.
