Two gases A and B are filled at the same pressure in separate cylinders fitted with frictionless movable pistons of radius rA and rB respectively. On supplying an equal amount of heat to both systems reversibly under constant pressure, the pistons of gas A and B are displaced by 16 cm and 9 cm respectively. If the change in their internal energy is the same, then the ratio rA / rB is equal to:
