Two identical particles are attached at the end of a light string which passes through a hole at the center of a table One of the partical is made to move in a circle on a table with angular velocity `omega_(1)` and the ther is made a move is a horizontal `omega_(2)` if `l_(1)`and `l_(2)` are the length the table , than in order that particle under down the table neither moves down nor move up the ratio` l_(1)//l_(2)` is
