Question

a person is in contact with the inner wall of a vertical hollow cylinder of radius 1m, remains in equilibrum with out slipping down as cylinder is rotated about its vertical axis with angular velocity 3.5rad/s. the minnimum cofficient of static friction between person and wall of cylinder such that the does not slip down is

Answer 1

Answer:

remains in equilibrium without slipping down as the cylinde is rotated about its own vertical axis with an angular velocity 3.5 rad/s. The ...

Answer 2

Answer:

Max. fs=μN=Mg

Also N=Mω

2

R

∴μ[M×(3.5)

×(1)]=M×10

⇒μ=0.8
