Question

A light spring of constant A = 90.0 N/n is attached vertically to a table (Fig. P15.55a). A2.00-g balloon is filled with helium (density = 0.180 kg/m)to a volume of 5.00 m and is then connected to the spring.causing it to stretch as shown in Figure P15.55b. Determine the extension distance L when the balloon is in equilibrium.
