Answer to Question #64840 in Mechanics | Relativity for Emmanuel

Question

An object of mass 500g is attached to a string of length 50cm which will break if the tension is 20N . The object is whirled in a vertical circle , the axis of rotation being at a height of 100cm above the ground. The angular speed is very slowly increased until the string breaks.In what position is this breakage likely to occur, and of what angular speed? Where will the object hit the ground?
