Physics - NLM Question with Solution | TestHub

In a rotor, a hollow vertical cylindrical structure rotates about its axis and person rest 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 2m and coefficient of static friction between the wall and person is 0•2, then the minimum speed at which the floor may be removed is $\left(\mathrm{g}=10\mathrm{m}/{\sec }^2\right)$
