A disc of radius 2 m is rotating with angular is to be put on the disc. Friction coefficient between disc and block is μ K ​ = 0.3 , then find the maximum distance from axis where the block can be placed without sliding

​ Friction force = centripetal force μ K ​ ( m g ) = m ω 2 x μ K ​ ⋅ g = ω 2 x 0.3 × 10 = ( 10 ) 2 x ⇒ x = 100 3 ​ m = 3 cm ​
