1.	Q. In a rotor, a hollow vertical cylinder rotates about its axis and a 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 withoutany floor. If the radius of the rotor is 2 m and the coefficient of static firction between the wall and the person is 0.2. Find the minimum speed at which the floor may be removed.
Answer» Answer: 10 m/s Explanation: $v = \sqrt{ \frac{rg}{ \alpha } } = \sqrt{ \frac{20}{0.2} } = 10ms$ PLS MARK this as BRAINLIEST..

Answer:

10 m/s

Explanation:

$v = \sqrt{ \frac{rg}{ \alpha } } = \sqrt{ \frac{20}{0.2} } = 10ms$
