A mass m rotating freely in a horizontal circle of radius 1 m on a frictionless smooth table supports a stationary mass 2m, attached to theother end of the string passing through smooth hole O in table, hanging vertically. Find the angular velocity of rotation.Solution) for block rotating on table...T = mv2/r where T is tensionand for block hanging vertically,T= mgmg= mv2/rv = root ( rg) =root(10)w= v/r=root(10)/1 = root ( 10)= 3.2 rad/sec
