A rod AB of length 2 m is hinged at point A in and its other end B is attached to a platform on which a block of mass m is kept. Rod rotates about point A maintaining angle θ=30∘ with the vertical in such a way that platform remains horizontal and revolves on the horizontal circular path. If the coefficient of static friction between the block and platform is μ=0.1, then find the maximum angular velocity in rad s-1 of rod so that the block does not slip on the platform.g=10ms−2
