Q. No.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 \(16~ \text{cm}\) and \(9~ \text{cm},\) respectively. If the change in their internal energy is the same, then the ratio \(r_A / r_B\) is equal to:
| 1. | \(\dfrac{2}{\sqrt{3}}\) | 2. | \(\dfrac{\sqrt{3}}{2}\) |
| 3. | \(\dfrac{4}{3}\) | 4. | \(\dfrac{3}{4}\) |
