A small bead of mass m = 1 kg is free to move on a circular hoop. The circular hoop has centre at C and radius r = 1 m and it rotates about a fixed vertical axis. The coefficient of friction between bead and hoop is `mu=0.5`. The maximum angular speed of the hoop for which the bead does not have relative motion with respect to hoop, at the position shown in figure is : (Take `g = 10 m//s^(2)`)

A

`(5sqrt2)^((1)/(2))`

B

`(10sqrt2)^((1)/(2))`

C
