Free Response Problems A small sphere of mass m and density D is suspended from an elastic spring. The spring is stretched by a distance X1. Determine the spring constant. The sphere is submerged into liquid of unknown density ρ < D. The new displacement of the spring is X2. On the diagram below show all the applied forces on the sphere when it is submerged. Determine the weight of the displaced liquid by the sphere. Determine the density of liquid. Express your result in terms of D, X1, X2.
