Two springs, each with force constant k and unstretched length l0, are connected in a straight line as shown in Fig. 11-34. (a) Find an expression for the work required to move the point of attachment between the two springs a perpendicular distance x from the equilibrium point. (b) Use the binomial expansion to find the first non-vanishing term in the expression for the work when x 0.
