A mass m in attached to a mass less string and swings in a horizontal circle, forming a conical pendulum, as shown in the figure. The other end of the string passes through a hole in the table and is dragged slowly so as to reduce the length l. The stringis slowly drawn up so that the depth h shown in the figure becomes half. By what factor does the radius (r) of the circular path of the mass m change?

1.	A mass m in attached to a mass less string and swings in a horizontal circle, forming a conical pendulum, as shown in the figure. The other end of the string passes through a hole in the table and is dragged slowly so as to reduce the length l. The stringis slowly drawn up so that the depth h shown in the figure becomes half. By what factor does the radius (r) of the circular path of the mass m change?
