Task id10685
The simplest hydrometer (a device for determining the density of a liquid), made of a round pencil with a diameter d = 8 mm and a metal ball with a diameter dsh = 5 mm attached to its base, has a weight G = 0.006 N. Determine the density of the liquid p if the cylindrical part of the hydrometer is immersed in it to a depth of h = 1.5 cm.
