A light spring that obeys Hooke's law has an unstretched length of 0.250 m. When an object of mass 2.0 kg is hung from the spring the length of the spring becomes 0.280 m. When the object is fully submerged in a liquid of density 1200 kg m-3, the length of the spring becomes 0.260 m. Calculate: a. The spring constant of the spring. b. The upthrust on the object. c. The volume of the object.
