A box has a weight of $15\,\text{N}$. It is standing on a horizontal surface, with face P touching the surface. How much does the pressure on the surface change if the box topples so that face Q is in contact with the surface?
- A$0.0040\,\text{m}^2/\text{N}$
- B$0.0067\,\text{m}^2/\text{N}$
- C$100\,\text{N m}^{-2}$
- D$250\,\text{N m}^{-2}$
