A rotor is rotating with a constant angular velocity `omega` about its own axis. At the centre of the rotaor a spring is fixed of natural length `(l_(0))` whose other end is connected to a block of mass m. Find the minimum vaule of coefficient of friction between block and rotor wall for which spring remains horizontal. The radius of rotor is `R (R lt l_(0))`.   img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/BSL_XI_RT_P13_E01_580_Q01.png" width="80%"
