Physics Question from JEE Main 2025 · 29 January, Shift 1

In a hydraulic lift, the surface area of the input piston is $6 \, \text{cm}^2$ and that of the output piston is $1500 \, \text{cm}^2$. If $100 \, \text{N}$ force is applied to the input piston to raise the output piston by $20 \, \text{cm}$, then the work done is _____ $\text{kJ}$.
