Two gases \(A\) and \(B\) are filled at the same pressure in separate cylinders with movable pistons of radius \(r_A\) and \(r_B\), respectively. On supplying an equal amount of heat to both the 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 \(r_A/r_B\) is equal to
1. \(\frac{4}{3}\)
2. \(\frac{3}{4}\)
3. \(\frac{2}{\sqrt3}\)
4. \(\frac{\sqrt3}{2}\)
