An object with weight $12\,\text{N}$ is at rest on a platform at the top of a container fitted with two pistons, as illustrated. The container holds a fixed mass of gas, and the pistons can move freely. The plunger is then pressed slowly $4.0\,\text{cm}$ to the right. Consequently, the object rises slowly by $0.50\,\text{cm}$. What is the amount of work done on the object?
- A$0.060\,\text{J}$
- B$0.48\,\text{J}$
- C$6.0\,\text{J}$
- D$48\,\text{J}$
