The diagram depicts a solid cube of weight $W$ and side length $L$. It is held on a frictionless spindle that goes through the centres of two opposite vertical faces, one of which is shaded. The spindle is then taken away and fitted again at a position $\frac{L}{4}$ to the right of where it was originally. If the shaded face is being viewed, what torque of the couple must now be applied to prevent the cube from toppling?
- A$\frac{WL}{2}$ anticlockwise
- B$\frac{WL}{2}$ clockwise
- C$\frac{WL}{4}$ anticlockwise
- D$\frac{WL}{4}$ clockwise
