A stone of mass 700 g is supported by a smooth horizontal surface and attached to a light inextensible string of length 0.6 m which will break if the tension in it exceeds 35 N. The other end of the string attached to a fixed-point O on the supporting surface. The stone is whirled in a horizontal circle. The angular speed is slowly increased with a constant angular acceleration until the string breaks. Calculate at what angular speed the break might occur and the liner velocity at this moment.
