Two blocks of masses 7 kg and 3 kg are connected by a spring of stiffness 1000Nm^(-1) and placed on a smooth horizontal surface. They are acted by horizontal forces of 72 N and 32 N in opposite directions as shown in the figure. When accelerations of the blocks are equal and constant, the extension of the spring is
