The spring in Figure CQ13.3 is stretched from its equilibrium position at x = 0 to a positive coordinate x0. The force on the spring is F0 and it stores elastic potential energy PEs0. If the spring displacement is doubled to 2x0, determine (a) the ratio of the new force to the original force, Fn/F0, and (b) the ratio of the new to the original elastic potential energy, PEsn/PEs0.
